I'm just making it clear so that all you Noncatholic Christians know your status. You are all pagans, one of a multitude of new paganisms invented since the 1500s, where your God is our God, He is God, you've got the right God, and that does set you apart from all the other paganisms who worship some other deity besides God. You're Christian pagans, Christian idolaters. You are our brethren, but we are separated.
Fact is that the Lord Jesus built a Church, one Church, and she is spoken of many times in the New Testament (not the "church in the wilderness" that trolls like to play like it's a card up their sleeve), and both secular and Church history records what has happened to this one Church in the intervening centuries between now and the Resurrection of Christ.
The Apostles were themselves and they created bishops, to oversee the Church. 1st and 2nd Timothy and Titus are NT books that were actually addressed to first generation bishops by the Apostle St. Paul, so we both read about bishops in books like Acts and in Peter's epistles where he addresses them, calling them there "elders", and we get to read what was written to just them, and not to the Church in general like other epistles. We know from Scripture that the consecration of a bishop was done by current bishops, through the imposition of their hands, and that the Apostles made bishops in this way. Timothy and Titus were made bishops by the imposition of Paul's hands. This process of bishops creating new bishops has gone on continually from the Apostolic era onward, and is still done today, by bishops who were created in the same tradition, by the same means, as those in the first century and in every century since then.
This pastorate of bishop, this office (cf. 1st Timothy 3:1), was instituted by the Apostles, and it exists to this day, in both Catholicism and in Orthodoxy, both traditions tracing their root to the Apostolic era. If you aren't under a bishop that was created in this same, biblical tradition, then you are a pagan, aka a Protestant in particular, you protest the office of a bishop that the Apostles instituted to oversee the one Church that the Lord Jesus built.
Upon Peter.
Just so you know where you stand. Your paganism may not allow it, but you are a sheep, and you have a Shepherd, and He has a fold for you, and you are outside the fold that He built for you.
All of you. Just so you know.
