I think only those who are convinced that what the Catholic Church teaches is true should become Catholic. I honestly am dismayed that so many godly Protestants are being abandonded by their denominations. And yes I consider it abandonment when a faithful Christian is told that the Holy Spirit is doing a new thing and God now blesses homosexual behavior. Or that cow farts are a matter for Easter reflection. Or that Jesus is a vehicle to the divine. Or Baptism shall be in the name of the Creator, Redeemer and Sustainer. It stinks and it is heartbreaking for so many non Catholics to see their denominations becoming liberal social clubs.
I pray that all Protestants can find a church home where the Reformed traditions they hold so dear are preached and practiced. Where the only one glorified is the Triune God.
