Here’s a point to consider:
Conversion from sin is a matter of a change of heart. This change of heart comes from repentance. Not faith.
In Catholic theology, the starting point is God calls and then we answer Yes or No.
Two examples:
- The Annunciation in which Our Lady answers with her Fiat.
- The Proclamation of the Kingdom: Repent for the Kingdom of God is at hand.
In both cases, we see the freedom of human will in action.
For we see throughout Sacred Scripture, the saints are called by God without any saving faith conversions needed. To my mind, the Protestant concept of saving faith conversion seems to require a sudden, dramatic and unalterable change of heart. Nowhere in Sacred Scripture do I see evidence of these types of conversions. Even Abraham and Saint Paul.
Saint Paul’s conversion on the Road to Damascus was the result of an awe inspiring moment of revelation that leads to guilt and then repentance, not the saving faith regeneration as you seem to teach.
God calls us and we have the free will to answer Yes or No. When we answer Yes, God offers us the grace we need as we put in the lifelong effort of conversion from sin. The Church has the 7 Sacraments from which we draw grace that we need to live holy lives pleasing to God.
In Protestant doctrine, man has no free will and that’s a contradiction of Scripture.
In comparison, your doctrines seem to require God forcing grace upon you, willing or not; and you then experience conversion. God forcing things on people would make God the sort of God that would force Himself on others. How is that a loving God who wants hearts to turn to Him in love and truth? If love is forced; is that truly love?
Depending on your tradition, it’s a one and done conversion or a lifelong one. Once you convert, your traditions only have two valid Sacraments: Baptism and Matrimony.
Now, from some of your arguments, I see that our Protestant brothers and sisters seem to argue that baptism by faith, no where to be seen in Sacred Scripture; occurs; which then seems to render the Sacrament of Baptism to be redundant.
