You didn’t learn anything while in the Church, therein lies the problem.
You are always a Catholic, and I think you know that. We wilcome you back at any time. Please sit down with a priest and get your questions answered.
let's see now...you leave the church which wrote the scriptures, (not actually wrote them but transcribed , protected, interpreted, authenticated, etc.etc. ) to join a "church" which sprang up 1,500or so years later and then you decide that the church is "truly off"....now I get it, you had a revelation and Jesus Himself told you that He blew it when He founded the Catholic church...at last I understand
no, you didn’t learn the RCC was “different” than scriptures, you “learned” it by cherry picking bible verses out of context.
It’s like a game of “gotcha”: stick up a straw man (A catholic dogma, and sometimes just a pious practice) and then find a verse against it, ignore all the early church fathers, and any verse that might support the Catholic point of view, and voila, instant “bad bad catholics”.
‘God, I thank you, that I am not like the rest of men, extortioners, unrighteous, adulterers, or any of those one billion immoral and deluded Catholics...I fast twice a week. I give tithes of all that I get.’
