Best not to use “the church” like a club (in both meanings of the word), cutie pie.
Albion Wilde;
I believe God is One God, in 3 Divine Persons (Father, Son and Holy Spirit]. Christ is the 2nd Person of the Holy Trinity and as a Divine Person has both a Divine Nature and human nature [Hypostatic Union]. Christ founded a Church, not Churches, and the Church is His Body [He is not 2 Persons, 1 Divine Person] and His Church is His Bride [Christ is not a Polygamous].
Thus, as the Nicene Creed says, I believe in One, Holy, Catholic and Apostolic Church. Period end of discussion. Now, as a Catholic I fully recognize that those other Apostolic Churches, the Orthodox, Oriental Orthodox and Assyrian Church of the East are valid Churches. They all have valid Bishops and valid Sacraments, hence those while n schism from us Catholics since 1054, 451, and 431 AD, nevertheless are in terms of Doctrine 99% in line with us.
While you protestants, those that have valid Trinitarian baptisms are indeed Christian, thus have valid sacramental baptism and I will concede have valid sacramental marriages since the ministers of the sacrament of marriage are the man and woman who make the sacred exchange of vows before God. So 2 sacraments. Protestants are much further from the true Apostolic faith while still have some connection to the Church. But protestant communities are not Churches, they are communities of baptized Christians.
So I don’t make judgments on protestants and their souls, God meets those where they are at and the sins of Formal heresy that the likes of Luther, Zwingli, Calvin, Crammer and Cromwell can’t be applied to modern protestants [they were Formal heretics].
Thus God’s grace for those protestants who are truly invincibly ignorant through no fault of their own can and will be saved, but not through the protestant faith.
So I have all the communion of saints in heaven to ask to pray for me, and fellow Catholics and we Catholics often on theological forums on Youtube will often pray for our Orthodox, Oriental Orthodox and Assyrian Church of the East brothers and sisters, who are much closer to us than you protestants [who are like split peas]
But I wish you well none the less.
