Tradition and Isaiah 6:3
About two weeks ago, having abandoned my belief in Biblical infallibility three weeks before that, I came to the conclusion that Tradition is important. Saint Paul of Tarsus I believe mentioned it several times in his letters, so Tradition is important.
My beliefs on Sola Scriptura are gone, as the Bible has so many blatant contradictions. My beliefs, however, are tending to swing between Trinitarianism and Arianism, all due to Isaiah 6:3, where it says: 'holy, holy, holy is the Lord of hosts, the whole world is full of His glory'.
Does anyone else believe that Isaiah 6:3 is a reference to the Trinity?
Thank you in advance for your replies.
