If the Trinity was only a Catholic tradition, I wouldn't accept it...But since the Trinity is all over the scriptures, I accept it as truth...
Iscool:
Show me in the Scriptures where the Holy Trinity is “formally defined”, ie. that God is One Divine Substance, yet three Distinct Persons who are all Divine Persons but are in a perfect communion of Love and thus so intimately related that there are “not 3 Gods” but One God.
Show me in the Sacred Scriptures where Christ, the Second Person of the Holy Trinity is formally defined as “a Divine Person” who has both a “Full Divine Nature” and “Full Human Nature” and those 2 Natures are not at odds or in confusion and both fully function in the Divine Person who is Christ.
The Bible does not speak on its own, it had to be interpreted by the Church, which St. Paul describes as the “pillar and Foundation of Truth” (cf 1 Timothy 3:15) and the Church doing the interpretation via the Church Fathers and Councils of the Early Church (Nicea 325, Constantinopile 381, Ephesus 431, and Chalcedon 451) were the “One Holy, Catholic and Apostolic Church” not your local protestant ecceslial community in backwoods America.
So when Timothy says we should pass on the traditions we have learned, you reject it?
Or does the Gospel according to Iscool excise that portion?
What about where Christ says, “I am the living bread”
What about the part in scripture where it says, the father uncreated, the son uncreated, and the holy spirit uncreated?
You believe all these things?
If you're going to reject the Papacy because the word "Pope" isn't in the Scriptures, you ought to reject the Trinity for the same reason. Plenty of a "Bible alone" groups already do. What makes you right, and them wrong? Remember, they claim to go by the "Bible alone" just like you do.
Like the rest of Protestantism, you pluck bits and pieces of Catholic tradition that you like -- stuff like the Trinity, Sunday worship, and the canon of Scripture -- pronounce it "Biblical," and adopt it as your own. There's far more attestation for the real presence of Christ in the Eucharist and the Papacy in the Scriptures than there is for any of the three things I mention above, but you reject both of them and accept the other stuff.
