Sometime during his life GK Chesterton discerned the death of Christendom and wrote a truly remarkable book of that title. Now Protestant America is coming to an end as well. As an observer of the breakdown of the USA and the church, I believe that Novus Ordo, Cardinal Robert Sarah (very much disliked by the Vatican), and other faithful Catholics, together with faithful orthodox Protestants, Eastern Orthodox, Lutherans, etc. share in common love for our Lord Jesus Christ, and hearts that seek Truth. Is it that in these evil days we are witnessing the emergence of the Lord’s faithful remnant? Personally, I believe this is so.
Sorry to disappoint you but while there is a remnant of salvific faith, that remnant of the Lord cannot be the admixture you describe, since the real basis Catholics for Catholic belief is not the only wholly inspired-of-God and substantive record of what the New Testament church believed (Scripture, esp. Acts-Rev.), but it is the magisterium of their church, past (for RadTadRcs) or present (for V2RCs).
Which promulgates distinctive Catholic teachings that are not manifest in that only wholly inspired substantive authoritative record
While all churches come short of the purity, purpose, probity and power of the prima NT apostolic church, yet the remnant are those who have at least had their "day of salvation" of Scriptural regeneration with it's profound basic effects thru personal repentant effectual faith to save them as lost sinners, on Christ's account.
And work to continue in the word of His grace. May we all be of such.
