There are two instances in the New Testament when Jesus told someone to “sin no more,” and they were each under very different circumstances. The first is when Jesus healed an invalid by the Pool of Bethesda (John 5:1–15). Afterward, Jesus found the man and told him, “See, you are well again. Stop sinning or something worse may happen to you” (verse 14). It is clear that Jesus knew what had caused the man’s condition. We are not told the specifics of the man’s physical impairment, but the context implies that it was caused by sinful choices. Jesus warned the man that he had been given a second chance and that he should make better choices. If the man returned to his sinful behavior, he would have wasted the opportunity Jesus gave him to live whole and forgiven.
The second instance is in the account of the woman taken in the act of adultery (John 8:3–11). When the woman’s accusers brought her before Jesus, expecting Him to pronounce judgment, He told them that the one who was without sin should throw the first stone. One by one, the condemning crowd left. Then Jesus told the woman, “Neither do I condemn you. Go and sin no more” (verse 11). She had been caught. She was guilty. She did deserve stoning according to the Law of Moses (Leviticus 20:10; Deuteronomy 22:22). But the religious leaders who had dragged her there had no concern for holiness. They were trying to trap Jesus into saying that the Law did not matter (verse 6). Jesus often reminded those religious leaders that He had not come to abolish the Law but to fulfill it (Matthew 5:17). He, as God, was the Author of the Law (2 Timothy 3:16). The Pharisees focused on the letter of the Law but missed the true spirit of it, which is given in Galatians 5:14: “The whole law can be summed up in this one command: ‘Love your neighbor as yourself.’” When Jesus refused to condemn the woman, He was not minimizing the importance of holiness. He was offering her the same kind of forgiveness He offers every one of us (Acts 3:19).
In saying, “Go and sin no more,” Jesus was not speaking of sinless perfection. He was warning against a return to sinful lifestyle choices. His words both extended mercy and demanded holiness. Jesus was always the perfect balance of “grace and truth” (John 1:14). With forgiveness comes the expectation that we will not continue in the same path of rebelliousness. Those who know God’s love will naturally want to obey Him (John 14:15).
Those who adhere to Sacred Scripture and Tradition have told the progressive modernists within the church that they are teaching against what Christ, St. Paul, etc have taught: “Neither do I condemn thee, go and sin no more.” Both. A message of conditional forgiveness.
In concert with what St. Paul wrote, those who have committed adultery or done anything per Gal. 5:19-21, 1 Cor. 6:9-10, can be absolved of sin and receive the Eucharist as long as certain criteria are met: sorrow for sin, true repentance, etc, etc.
But the progressive modernists instead support a message where just about anything goes on this, divorce, women “pastors” being allowed, etc.
As someone else said, it’s a false message of mercy from them based upon the lie of supposedly God-allowed “tolerance” and “inclusivity.”
