The Biblical Basis for the Trinity: Five Propositions

1. There is one, and only one, God.
   Deut. 4:35, 39; 6:4; 32:39; 2 Sam. 7:22; Ps. 86:10; Isa. 43:10; 44:6-8; 46:9; John 5:44; 17:3; Rom. 3:29-30; 16:27; 1 Cor. 8:4; Gal. 3:20; Eph. 4:6; 1 Thess. 1:9; 1 Tim. 1:17; 2:5; James 2:19; 1 John 5:20-21; Jude 25.
2. The person of the Father is God.
   John 6:27; Eph. 4:6; Col. 1:2-3; 2 Pet. 1:17.
3. The person of the Son is God.
   John 1:1; 5:17; 8:58; 10:30; 20:28; Phil. 2:6; Col. 2:9; Titus 2:13; Heb. 1:8; 2 Pet. 1:1.
4. The person of the Holy Spirit is God.
   Gen. 1:2; John 14:26; Acts 5:3-4; 13:2, 4; 28:25; Rom. 8:11; Eph. 4:30.
5. The Father, Son, and Holy Spirit are distinct and simultaneously distinguishable persons.
   Matt. 28:19; Luke 3:22; John 15:26; 16:13-15; 2 Cor. 13:14.

These biblical propositions logically imply that since there is only one God and the three distinct persons are all called God, then the three persons must be the one God.

The three persons have the titles, attributes, and perform the works of Deity. The Bible attests in numerous ways to the full and undiminished deity of the Father, the Son, and the Holy Spirit. John 1 and Hebrews 1 establish the Trinity beyond doubt.
