I was limited to Unitarian studies, actually. I have been a Unitarian since converting two years ago, so I had no desire to look into Catholicism or eastern Christianity. However, I have now accepted the trinity, not on the basis of Church history, but on the basis of Scripture alone. I have to disagree with you in that the Bible does very clearly state the trinity. I did not need to rely on the writings of the early Christians to define it. Had it not been clearly and completely defined in the Bible, I would still reject it. This is primarily because I reject the Catholic concept of Sacred Scripture and Sacred Tradition (as it stands).
I used to find the trinity to be a rather poorly supported doctrine, but it was primarily because many Trinitarians misrepresented it. I had debated the doctrine of the trinity with many people and none of them presented it as well as James White did in his publication The Forgotten Trinity.
Let’s continue with the example you gave, which is the doctrine of the trinity. There is not one verse that spells it out for us. There is not one verse that tells us Jehovah is triune in nature, that is, consisting of the Father, the Son, and the Spirit. Yet the Bible does reveal this teaching through a network of scriptures (Matthew 3:16-17, 11:27, 17:1-9, 27:46, John 1:18, 14:16-17. The Pre-existence of the Son: Colossians 1:13-17, Hebrews 1:2-3, John 1:1; Colossians 2:9, John 20:28, Titus 2:13, 2 Peter 1:1, John 1:18; identification as Yahweh: John 6:39-41/Isaiah 6, Hebrews 1:10-12/Psalm 102:25-27, etc.). I can say the same thing regarding sola scriptura. Consider the following texts (NASB):
2 Timothy 3:16 -
All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness;
What did Jesus and the apostles appeal to?
Matthew 4:4 -
But He answered and said, “It is written, ‘Man shall not live on bread alone, but on every word that proceeds out of the mouth of God.’”
Matthew 4:7 -
Jesus said to him, “On the other hand, it is written, ‘You shall not put the Lord your God to the test.’”
Matthew 4:10 -
Then Jesus said to him, “Go, Satan! For it is written, ‘You shall worship the Lord your God, and serve Him only.’”
Acts 17:2 -
And according to Paul’s custom, he went to them, and for three Sabbaths reasoned with them from the Scriptures,
Acts 17:11, 12 -
Now these were more noble-minded than those in Thessalonica, for they received the word with great eagerness, examining the Scriptures daily to see whether these things were so. Therefore many of them believed, along with a number of prominent Greek women and men.
Acts 18:28 -
for he powerfully refuted the Jews in public, demonstrating by the Scriptures that Jesus was the Christ.
1 Corinthians 1:19 -
For it is written, “I WILL DESTROY THE WISDOM OF THE WISE, AND THE CLEVERNESS OF THE CLEVER I WILL SET ASIDE.”
Do you recall what Jesus said to the Pharisees regarding tradition?
Matthew 15:3-6 -
And He answered and said to them, "Why do you yourselves transgress the commandment of God for the sake of your tradition? For God said, ‘Honor your father and mother,’ and, ‘He who speaks evil of father or mother is to be put to death.’ But you say, ‘Whoever says to his father or mother, “Whatever I have that would help you has been given to God,” he is not to honor his father or his mother.’ And by this you invalidated the word of God for the sake of your tradition.
Now, let’s clearly consider what Jesus is talking about. This was not the layman, pagan, tradition that local people had. Jesus was speaking to the Pharisees about their religious traditions!
