The Bible affirms a foundational truth that there is only one God (Deuteronomy 6:4; Isaiah 43:11; 44:6; Mark 12:29; 1 Corinthians 8:4; Ephesians 4:6; Timothy 2:5). However, it also presents a profound mystery in which God exists as three parts which are coequal and eternal: the Father, the Son, and the Holy Spirit. While the word “Trinity” never appears in the text, the concept is woven throughout Scripture. By comparing relevant passages, we arrive at this factual conclusion. We rely not on human wisdom, but on the Holy Spirit to interpret these spiritual realities (1 Corinthians 2:13).
At the same time, the Bible plainly indicates a plurality within God’s nature, consisting of three eternal and coequal persons: the Father, the Son, and the Holy Spirit, each the same in basic nature, but distinct in existence.
Although the word Trinity does not appear in the Bible, the doctrine of the Trinity is a factual conclusion, reached by comparing and combining relevant scriptural truths. “We are setting these truths forth in words not taught by human wisdom but taught by the Holy Spirit, combining and interpreting spiritual truths with spiritual language [to those who possess the Holy Spirit]” (1 Corinthians 2:13 AMPLIFIED).
