Catholicism is the ONLY true Christian church in history.
the various zillions of "denominations" are just that...wannabees
LOL. Horse hockey. We all know the OTC, is the First United Church ⛪ of the Navigators. It was started by Jesus. 👍 They are not into works based religions. I gave that up for lent. Having assurance of salvation is a beautiful thing. I am reasonably sure you wish you had it. So, do you feel lucky? 🍀
Was the NT church the universal church? Yes it was. It was based on faith in Christ and Christ alone.
However, what we've seen over time is the deportation from that. Roman Catholicism came about around 200-300 AD.
Rome has advanced so many false teachings it's hard to identify them all. Roman Catholicism is essentially Jesus+Mary+Works+Baptism+, etc+etc.
