Hey True, both Mormons and Catholics believe in a physical church that has an authoritative hierarchy. Sacred Tradition is taught as coming from the same divine wellspring as Sacred Scripture, in Catholicism. I think it is debatable, and has been debated often on these forum, whether every papal text and every church council is infallible. That being said, mainline Protestants generally accept the first seven councils as authoritative.
I looked at a lot of different religions, not just Christian. Speaking for myself, the overriding thing with Protestant denominations is that they were all started by some guy, same as Mormonism. I see Mormonism as the ultimate result of Protestantism. They both have a view that Jesus left His church and so it is we must go figure out where He went. Add to that, that sola scripture is not really sola scripture, and it wasn’t hard for me to decide where to go. I’m Roman Catholic.
But, another but , Protestantism and Roman Catholicism, from a former Mormon POV, have few doctrinal differences. Really, some of the main points of contention as argued on these forum are trivial, when compared to how far off the rails Mormonism takes people. I’m happy when I see any former Mormon move to any Christian religion, where they can receive a valid baptism, as so many former Mormons go atheist…as I did for most of my life.
