Abel: I mean we believe in the trinity and yet nowhere in the bible is trinity mentioned and it is by revelation of God's word that we know it is true. It is the same for Gappists.
Abel, are you serious???!!! ONLY by revelation??? The Trinity is referenced all over the Bible. And CLEARLY so!
The Trinity referenced across the Old Testament:
Who has ascended into heaven and descended? Who has gathered the wind in His fists? Who has wrapped the waters in His garment? Who has established all the ends of the earth? What is His name or His Son's name? Surely you know! (Proverbs 30:4)
Then a shoot will spring from the stem of Jesse, And a branch from his roots will bear fruit. And the Spirit of the LORD will rest on Him, The spirit of wisdom and understanding, The spirit of counsel and strength, The spirit of knowledge and the fear of the LORD. (Isaiah 11:1-2)
"Behold, My Servant, whom I uphold; My chosen one in whom My soul delights. I have put My Spirit upon Him; He will bring forth justice to the nations. (Isaiah 42:1)
"Come near to Me, listen to this: From the first I have not spoken in secret, From the time it took place, I was there. And now the Lord GOD has sent Me, and His Spirit." (Isaiah 48:16)
The Spirit of the Lord GOD is upon Me, Because the LORD has anointed Me To bring good news to the afflicted; He has sent Me to bind up the brokenhearted, To proclaim liberty to captives, And freedom to prisoners; (Isaiah 61:1)
In all their affliction He was afflicted, And the angel of His presence saved them; In His love and in His mercy He redeemed them; And He lifted them and carried them all the days of old. But they rebelled And grieved His Holy Spirit; Therefore, He turned Himself to become their enemy, He fought against them. (Isaiah 63:9-10)
Not only is the plurality of God found in the Old Testament, but the members of the triunity are also defined. Several Old Testament verses tell us that God is our Father:
"Do you thus repay the LORD, O foolish and unwise people? Is not He your Father who has bought you? He has made you and established you. (Deuteronomy 32:6)
"He will cry to Me, 'Thou art my Father, My God, and the rock of my salvation.' (Psalm 89:26)
For a child will be born to us, a son will be given to us; And the government will rest on His shoulders; And His name will be called Wonderful Counselor, Mighty God, Eternal Father, Prince of Peace. (Isaiah 9:6)
For Thou art our Father, though Abraham does not know us, And Israel does not recognize us. Thou, O LORD, art our Father, Our Redeemer from of old is Thy name. (Isaiah 63:16)
But now, O LORD, Thou art our Father, We are the clay, and Thou our potter; And all of us are the work of Thy hand. (Isaiah 64:8)
"Have you not just now called to Me, 'My Father, Thou art the friend of my youth? (Jeremiah 3:4)
"Then I said, 'How I would set you among My sons, And give you a pleasant land, The most beautiful inheritance of the nations!' And I said, 'You shall call Me, My Father, And not turn away from following Me.' (Jeremiah 3:19)
That God is the Son is also found in the Old Testament:
"I will surely tell of the decree of the LORD: He said to Me, 'Thou art My Son, Today I have begotten Thee. (Psalm 2:7)
Do homage to the Son, lest He become angry, and you perish in the way, For His wrath may soon be kindled. How blessed are all who take refuge in Him! (Psalm 2:12)
Who has ascended into heaven and descended? Who has gathered the wind in His fists? Who has wrapped the waters in His garment? Who has established all the ends of the earth? What is His name or His Son's name? Surely you know! (Proverbs 30:4)
"I kept looking in the night visions, And behold, with the clouds of heaven One like a Son of Man was coming, And He came up to the Ancient of Days And was presented before Him. "And to Him was given dominion, Glory and a kingdom, That all the peoples, nations, and men of every language Might serve Him. His dominion is an everlasting dominion Which will not pass away; And His kingdom is one Which will not be destroyed. (Daniel 7:13-14)
