If Catholicism and Eastern Orthodoxy were both fallen I’d be an agnostic atheist.
All the various forms of Protestantism are illogical IMO, and Judaism and Islam don’t recognize Christ as God. If Jesus isn’t God then I don’t feel any religion has formed a coherent theology about exactly what and who God is.
Christ is the centerpiece by which my faith stands or falls, and the Catholic and Eastern Orthodox faiths IMO are the only fully logical forms of Christianity.
Luckily, I believe the Catholic Church is indefectible and here to stay… And I have no reason at all or indicator to believe otherwise or even doubt. Pope Francis is a beaming Image of Christ and every word he speaks is full of grace… I feel so blessed to be in communion with such a spiritual giant as our Holy Father.
Eastern Orthodoxy though is in dire straits… I have doubts it will exist in 2030 the way it exists today. The whole EO communion IMO is bursting at the seems and ready to collapse on itself.
