Below is what I wrote and I stand by it.
“In John 8:11 “And she said, No man, Lord. And Jesus said, Neither do I condemn thee: go thy way; from henceforth sin no more.“ These are the words that came directly from the lips of Christ and it is the perennial teaching of the Church.
Among many other methods, Christ used parables to teach and communicate his message of love and salvation to all mankind. Certainly, no one particular parable can be regarded as the complete teaching of Christ. In this parable, the prodigal son abandoned his sinful way and wanted to be united with his father.
Catholicism involves both scriptures and sacred Tradition. I trust you did not mean that just because, in this parable, the father did not use the words “sin no more”, there is no need for repentance for sins be forgiven. If that were the case, Christ lied to the world, and the Catholic Church has perpetuated that lie for the past 2,000 years.
I am reminded of the Act of Contrition:
“O my God, I am heartily sorry for having offended Thee, and I detest all my sins, because I dread the loss of heaven, and the pains of hell; but most of all because they offend Thee, my God, Who are all good and deserving of all my love. I firmly resolve, with the help of Thy grace, to confess my sins, to do penance, and to amend my life.””
It is contrary to the teachings of Christ and the perennial teachings of the Church to advance the position that there is no need to repent for sins be forgiven. This applies to all of us sinners. A lot of great things have been written about this great parable and it is not possible to fullly discuss it in a few posts. It is true that the father in the parable did not specifically mention the words “sin no more”. But it does not nullify what Christ Himself said elsewhere in the Gospels. I know one thing for sure. This parable does not and can not contradict the words spoken from the lips of Christ “to sin no more.”
