For seven days, Days 8 through 13, this series has been examining what the gospel is not. Church membership. Baptism. Emotional experience. Moral living. The sinner’s prayer formula. And the false assurance that each of these substitutions produces. Today, Day 14, we step back from the specific examinations and ask the larger historical question that explains why every one of these substitutions exists in the first place.
How did we get here? How did the simple four sentences Paul gave in 1 Corinthians 15, the sentences he declared were of first importance, sufficient, complete, accumulate enough additions, supplements, and substitutions to produce the landscape we have been examining? How does something as clear as Christ died for our sins, He was buried, He rose again, according to the scriptures become obscured under layers of sacramental theology, experiential requirements, membership processes, moral frameworks, and prayer formulas?
The answer is not a conspiracy. It is not that sinister men sat in dark rooms and deliberately plotted to corrupt the gospel. The answer is both simpler and more sobering than that. And it is the answer Jesus gave when He addressed exactly the same phenomenon in His own day.
What Jesus Said About How This Happens
“Full well ye reject the commandment of God, that ye may keep your own tradition. For Moses said, Honour thy father and thy mother; and, Whoso curseth father or mother, let him die the death: but ye say, If a man shall say to his father or mother, It is Corban, that is to say, a gift, by whatsoever thou mightest be profited by me; he shall be free. And ye suffer him no more to do ought for his father or his mother; making the word of God of none effect through your tradition, which ye have delivered: and many such like things do ye” (Mark 7:9-13).
The target of Jesus’s rebuke was not paganism. It was not the Romans who governed Palestine with pagan religion at their backs. It was the most religiously sophisticated tradition in first-century Judaism, the accumulated interpretive framework of the Pharisees and scribes, built over centuries by sincere and learned men who were genuinely attempting to apply the Word of God to everyday life.
The Corban ruling was a specific example. A man could declare his property Corban, dedicated to God, and thereby exempt himself from the obligation to use it to support his elderly parents. The tradition was built by men who valued religious dedication and the honoring of commitments to the temple. It was not built by men who wanted to dishonor their parents.
But the tradition had the effect of making void the plain commandment of God, honor your father and your mother, through an elaborate religious mechanism that allowed a man to fulfil the letter of religious obligation while violating the spirit of the moral law.
And Jesus says: making the word of God of none effect through your tradition. This is the mechanism. Not malice. Tradition. Sincere, well-intentioned, carefully constructed tradition, that accumulates over time until it occupies the space that the plain Word of God was always meant to occupy.
The Pattern Across Church History
The history of Christian theology from the first century to the present is, in one significant dimension, the history of this pattern repeating itself. Each addition to the simple gospel followed the same trajectory that Jesus identified in Mark 7. It began with a genuine concern. It was developed by sincere people. It accumulated over time. It acquired the weight of age and consensus. And eventually it occupied, partly or fully, the space that belonged to the plain gospel of 1 Corinthians 15.
The second century — the first generation of post-apostolic church leaders faced a genuine pastoral problem: how do you distinguish genuine believers from the crowds who attached themselves to Christian communities for social or political reasons, or who professed faith without genuine inward transformation? The catechumenate developed, a structured period of instruction and examination before baptism. Sincere concern. Genuine wisdom. And the beginning of the process by which baptism became progressively more loaded with theological significance, until by the third century it was widely understood as the specific moment of the new birth rather than its public declaration.
The third and fourth centuries — as Christianity moved from persecuted minority to imperial religion, the pressure to define authentic Christianity intensified. The church developed increasingly elaborate structures for distinguishing insiders from outsiders, genuine converts from nominal members. The sacramental system expanded. The clergy developed as a distinct mediating class. Confession and penance emerged as mechanisms for managing the ongoing sin of baptized members. Each development addressed a genuine concern. Each one added something to the plain gospel.
The medieval period — by the high medieval period, the soteriological system of Western Christianity had accumulated centuries of addition. The Mass had become understood as a propitiatory sacrifice, a re-presentation of Calvary that applied the merits of Christ to specific recipients through the priestly action. Purgatory had developed as an intermediate state in which the temporal penalties of sin were purged before the soul could enter the presence of God. Indulgences provided a mechanism for reducing the time spent in purgatory through acts of piety, pilgrimage, or financial contribution. The treasury of merit, the accumulated good works of the saints, available for distribution through the church’s authority, supplemented the individual believer’s insufficient record.
Each of these had theological arguments behind it. Each was the product of centuries of sincere reflection by brilliant men. And taken together, they had produced a soteriological system in which the plain gospel of Christ crucified and risen, received through repentance and faith alone, was almost entirely obscured behind the elaborate institutional machinery of medieval Catholic soteriology.
The Reformation — Luther’s rediscovery of Romans 1:16-17 and Romans 4-5 was not the introduction of a new idea. It was the recovery of what Paul had given in 1 Corinthians 15 and had explained in Romans and Galatians, the plain gospel, freed from the accumulated additions of fifteen centuries. The Reformation watchwords, Sola Scriptura, Sola Fide, Sola Gratia, Solus Christus, Soli Deo Gloria, were not innovations. They were restorations. The rediscovery of the simplicity.
But the Reformation did not end the pattern. It could not end the pattern, because the pattern is not produced by one institution or one tradition. It is produced by the consistent human pressure to add to what God has given, to supplement what God has declared sufficient, to improve what God has made simple.
The post-Reformation centuries — within a generation of Luther’s stand at Worms, Protestant Christianity was producing its own additions. Covenant theology added the concept of the covenant of works, binding Adam and humanity to a legal requirement that shaped the understanding of how Christ’s atonement operated, in ways that went considerably beyond the specific language Paul used. Baptist traditions added the requirement of believer’s baptism as the condition of church membership in ways that sometimes moved baptism back toward a condition of salvation. Revivalism added the anxious bench, the altar call, and eventually the sinner’s prayer, creating a mechanism of salvation-by-decision that introduced a new version of the old problem.
The twentieth century — the charismatic movement added tongues as the evidence of Spirit baptism. The prosperity gospel added seed-faith giving as the activation mechanism for covenant blessing. The NAR added contemporary apostolic authority as a necessary supplement to the closed canon. The therapeutic movement added emotional wholeness as the content of salvation.
Each of them added something Paul never included in the four sentences.
Why the Pattern Never Stops
The pattern continues because the pressures that produce it never stop.
The pressure of pastoral concern. Every addition began as an attempt to address a genuine pastoral problem. How do we distinguish genuine converts from nominal ones? How do we provide ongoing care for believers who continue to sin after conversion? How do we give ordinary people a tangible sense of encounter with God? Each of these is a legitimate concern. The problem is the solution, the consistent tendency to address genuine pastoral concerns by adding to the gospel rather than by applying the gospel more deeply.
The pressure of institutional interest. As soon as Christianity had institutions; churches, hierarchies, councils, those institutions had an interest in maintaining their mediating position between the individual and God. A gospel that requires nothing beyond genuine repentance and faith in Christ alone is a gospel that requires no institutional mediation. The simpler the gospel, the less indispensable the institution. The more elaborate the sacramental or prophetic or experiential requirements, the more indispensable the institution that provides them.
The pressure of human religious nature. The simple gospel is not instinctively satisfying to the religious impulse. The religious impulse wants something to do, something to contribute, something that makes the standing before God feel earned or at least participated in. Grace alone, the pure, unearned, uncontributed gift of God, is psychologically uncomfortable for creatures who instinctively want to justify themselves. The additions are, in part, the religious instinct’s attempt to make room for the self in the transaction of salvation.
“There is a way that seemeth right unto a man, but the end thereof are the ways of death” (Proverbs 14:12). It seems right that there should be something for the person to do. That the vast, cosmic, eternal work of divine redemption should have some hook on which human contribution can hang. That the standing before God should require not only receiving but also doing something, however small, however supplementary.
It seems right. And following what seems right has produced fifteen centuries of accumulated additions that have obscured the simplicity that Paul feared the Corinthians would lose.
What This Means for What Comes Next
Tomorrow, Day 15, this series enters its third major section. We have spent seven days on what the gospel is. We have spent seven days on what it is not. Now we spend seven days on the five specific systems that represent the most significant and most widespread gospel additions in the contemporary church.
Roman Catholicism. The Charismatic movement. The New Apostolic Reformation. Legalism. The Prosperity Gospel. Each of these will be examined with the historical framework of today’s post in view. None of them arose from malice. Each of them arose from the same pattern Jesus identified in Mark 7, sincere concern, accumulated tradition, the word of God made of none effect. Each of them will be measured not against the accumulated tradition of any other institution, but against the four sentences of 1 Corinthians 15.
And each examination will be followed by the same thing that Jesus followed His rebuke of the Pharisees with, an invitation. Not to a different tradition. To the Word itself. To the simplicity that is in Christ, stripped of every addition that men have placed alongside it.
“Making the word of God of none effect through your tradition.” — Mark 7:13 KJV
