Though the word “Trinity” is not explicitly found anywhere in the Bible, the teaching that there are three individual personalities of divine nature known in the New Testament as the Father, Son, and Holy Spirit is thoroughly scriptural and has been generally acknowledged by the writers of “Christendom” since the apostolic age.
Now, there are many biblical concepts that Christians believe in that don’t have a specific word describing them used in the Bible. For example, the word “bible” is not found in the Bible, but we use it anyway to describe the Bible.
Likewise, “omniscience” which means “all-knowing,” “omnipotence” which means “all-powerful,” and “omnipresence” which means “present everywhere,” are words not found in the Bible either, but we use them to describe the attributes of God. We don’t have to see a specific word in the Bible in order for the concept it describes to be true.
Following are some other words that the Bible does not use, but the concepts are mentioned:
● Atheism is the teaching that there is no God. “The fool has said in his heart, ‘There is no God'”(Psalm 14:1).
● Divinity which means divine quality or godlike character. Yet, we speak of the godlike quality of the Lord God. See Psalm 139.
● Incarnation which means the word (God) who became flesh. Yet, this is definitely taught in the Bible (John 1:1, 14).
● Monotheism is the teaching that there is only one God (Isaiah 43:10; 44:8).
● Rapture is the teaching that the Christians who are alive when Jesus returns will be caught up to meet Him in the air (1 Thessalonians. 4:16-18).
The term “trinity” is a contraction of “tri” (meaning three), and “unity” (meaning one): “tri” + “unity” = “trinity“.
What the Holy Trinity is Not!
● It is not three Gods
● The Trinity is not the Father, Mary and Jesus.
Old Testament Evidence of Divine Plurality
“In the beginning God [Elohim — plural] created [bara — singular]” (Genesis 1:1)
“And God said, Let us make man in our image, after our likeness” (Genesis 1:26).
“Come, let us go down, and there confound their language” (Genesis 11:7).
“And I heard the voice of the Lord, saying, Whom shall I send, and who will go for us?” (Isaiah 6:8).
“Remember also thy Creator [Hebrew plural] in the days of thy youth” (Ecclesiastes 12:1).
This is but a fractional sampling of a vast amount of Old Testament evidence for the plural personalities of deity.
New Testament Evidence of Divine Plurality
When He had been baptized, Jesus came up immediately from the water; and behold, the heavens were opened to Him, and He saw the Spirit of God descending like a dove and alighting upon Him. And suddenly a voice came from heaven, saying, “This is My beloved Son, in whom I am well pleased.” (Matthew 3:16-17 NKJV)
Notice, the Father and Spirit present at the baptism of the Son.
Similarly, “And whosoever shall speak a word against the Son of man, it shall be forgiven him; but whosoever shall speak against the Holy Spirit, it shall not be forgiven him” (Matthew 12:32).
The contrast here between the Son and the Holy Spirit plainly shows that they are not identical in personality. These two arguments make it certain that Christ was neither the Father nor the Spirit.
For the law of the Spirit of life in Christ Jesus has made me free from the law of sin and death. For what the law could not do in that it was weak through the flesh, God did by sending His own Son in the likeness of sinful flesh, on account of sin: He condemned sin in the flesh. (Romans 8:2-3 NKJV)
The grace of the Lord Jesus Christ and the love of God, and the fellowship of the Holy Spirit be with you all. (2 Corinthians 13:14 Amplified)
● The grace of the Lord Jesus Christ
● The love of God
● The Fellowship of the Holy Spirit
For through Him we both have access by one Spirit to the Father. (Ephesians 2:18 NKJV)
If you are insulted and reviled for [bearing] the name of Christ, you are blessed [happy, with life-joy and comfort in God’s salvation regardless of your circumstances], because the Spirit of glory and of God is resting on you [and indwelling you—He whom they curse, you glorify]. (1 Peter 4:14 NKJV)
The Book of Acts
Therefore being exalted to the right hand of God, and having received from the Father the promise of the Holy Spirit, He poured out this which you now see and hear. (Acts 2:33 NKJV)
Then Peter said, “Ananias, how is it that Satan has so filled your heart that you have lied to the Holy Spirit……..You have not lied just to human beings but to God.” (Acts 5:3-4)
Notice the Holy Spirit is called God.
