A “Trinitarian” is one who believes that “God is one God who at the same time subsists in three Persons: the Father, the Son, and the Holy Spirit.” A “Unitarian” is one who believes that “God is one entity or Person” and thus they reject the belief that God subsists in three Persons. We firmly believe that the Bible teaches, from cover to cover, that God is a holy Trinity made up of the Father, the Son, and the Holy Spirit. Let’s consider scriptures that teach that they are co-equal and share the same attributes.

1) Each Person is called God. Ephesians 1:2 reads “Grace, to you, and peace, from God our Father…” John 1:1 says “In the beginning was the Word, and the Word was with God, and the Word was God.” Acts 5:3-4 states “Why hath Satan filled thine heart to lie to the Holy Ghostthou hast not lied unto men, but unto God.”

2) Each Person is Eternal. Psalm 90:2 declares “…from everlasting to everlasting, thou art God.” Hebrews 1:8 reads “But unto the Son He saith, Thy throne, O God, is forever and ever.” Hebrews 9:14 says “How much more shall the blood of Christ, who through the eternal Spirit offered Himself without spot to God…”

3) Each Person is Omniscient. 1 John 3:20 states “God is greater than our heart, and knoweth all things.” John 16:30 says concerning the Lord Jesus, “Now are we sure that Thou knowest all things, and needest not that any man should ask Thee: by this we believe that Thou camest forth from God.” 1 Corinthians 2:10-11 says “But God hath revealed them unto us by His Spirit for the Spirit searcheth all things, yea, the deep things of Godthe things of God knoweth no man, but the Spirit of God.”

4) Each Person is Omnipresent. Jeremiah 23:23-24 reads “Am I a God at hand, saith the LORD, and not a God afar off? Can any hide himself in secret places that I shall not see him? saith the LORD. Do not I fill heaven and earth? saith the LORD.” In Matthew 18:20 the Lord Jesus says, “Where two or three are gathered together unto My name, there am I in the midst of them.” Psalm 139:7 declares “Where can I go from Your Spirit? Or where can I flee from Your presence” (NKJV).

We could multiply scriptures which teach the blessed truth of the Trinity, but we will close with citing two more references where all three Persons are referred to in the same verse. Just before the Lord Jesus ascended to heaven He gave the following commission to His disciples in Matthew 28:19, “Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit” (NKJV). In 2 Corinthians 13:14 the apostle Paul concluded his letter with this benediction, “The grace of the Lord Jesus Christ, and the love of God, and the communion of the Holy Spirit be with you all” (NKJV). It would have been blasphemy for the Lord Jesus and the apostle Paul to have put the Father, the Son, and the Holy Spirit on equal footing if each Person was not truly God, co-equal to one another and sharing the same Divine attributes. But they were stating the precious truth that we have been considering, that God is indeed “one God who at the same time subsists in three Persons.”  (178.4)  (DO)
