Is it possible for a Catholic to understand Catholicism and still “convert” ?
Why I am asking. Is because it seems it is pretty clear that many believe "If you understood Catholicism, you would be a Catholic "?
Your final point is absolutely correct
WHY?
Because logically, morally and biblically in TRUTH there can be only:
One True God [the 1st Commandment]
One True Church [My People in the OT Exo 6:7 and “MY Church” Mt 16:18 [singular] in the NT
One set of faith beliefs as even God can do nothing more
Eph.4 Verses 1 to 7
[1] I therefore, a prisoner for the Lord, beg you to lead a life worthy of the calling to which you have been called, [2] with all lowliness and meekness, with patience, forbearing one another in love, [3] eager to maintain the unity of the Spirit in the bond of peace.
[4] There is one body and one Spirit, just as you were called to the one hope that belongs to your call, [5]
one Lord, one faith, one baptism, [6] one God and Father of us all, who is above all and through all and in all.
[7] But grace was given to each of us according to the measure of Christ’s gift"
Further evidence of this lies in the indisputable FACT that any and all “churches” are defacto defined by their freely chosen set of faith beliefs, which identify THEM
After 2,000 years Catholicism still retains ONLY One set of TRUE faith beliefs.
