The Trinity Explained: Can We Defend it Biblically?

One teaching that distinguishes Christianity from all other religions is the extremely challenging doctrine of the trinity. At face value it seems simple enough; three persons, one God. But like God Himself, it is a concept that is as deep and mysterious as it is unfathomable. Is it biblical? Is it True? Let's find out.

The word “Bible” is derived into English through Latin which came from the Greek word biblia (books).
βίβλῳ (biblō) book is found 129 times in NIV and 181 times in the KJV.
It is Strong's Concordance number 976. "biblos".
So no we don't find the Latin word "bible" in our English translations but instead we find the English word "book" or sometimes as "scrolls".
But the word Trinity, or any other language equivalent of it (τριάδα triáda in Greek), or (trinitas in Latin), is not found even once. Even though they already had the words to express it for hundreds of years before the New Testaments or the Septuagint.
In ancient Greece, and Rome, the concept of things being in arranged in threes was popular in all their philosophies and culture. For example, (The One, the Love, and the Wisdom). Triumvirate (Latin) was a political arrangement of three equal rulers. The first being in the late Roman Republic: Gnaeus Pompeius Magnus, Marcus Licinius Crassus, and Gaius Julius Caesar.

I get your point... however. the English word "Bible" is not used in the Bible, except on the cover. Even if the cognate for Trinity can't be found in the Bible, the concept is clearly there.
