“No - I am sure the goal isn’t to divide Christians. The goal is to increase the probability of salvation for non-Catholics by having them come into the Catholic Church.”
And what a bang up job some are doing here with that, huh?
FRiendly advice...take the example of the apostles and preach the Gospel (see 1 Corinthians 15). When one does this they are evangelizing not preaching catechism. The former always comes before the latter in the NT.
1 Corinthians 15:1-11 KJV
Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand; By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain. For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures: And that he was seen of Cephas, then of the twelve:
After that, he was seen of above five hundred brethren at once; of whom the greater part remain unto this present, but some are fallen asleep. After that, he was seen of James; then of all the apostles. And last of all he was seen of me also, as of one born out of due time. For I am the least of the apostles, that am not meet to be called an apostle, because I persecuted the church of God. But by the grace of God I am what I am: and his grace which was bestowed upon me was not in vain; but I laboured more abundantly than they all: yet not I, but the grace of God which was with me. Therefore whether it were I or they, so we preach, and so ye believed.
Matthew 18:15-17
New International Version (NIV)
Dealing With Sin in the Church
15 “If your brother or sister[a] sins,[b] go and point out their fault, just between the two of you. If they listen to you, you have won them over. 16 But if they will not listen, take one or two others along, so that ‘every matter may be established by the testimony of two or three witnesses.’[c] 17 If they still refuse to listen, tell it to the church; and if they refuse to listen even to the church, treat them as you would a pagan or a tax collector.
Sometimes catechism might take primacy over evangelization.
