Every so often, I see some Christians in some unconventional movements who want to deny the trinity. This seems to happen more often recently.
I hear this same argument from Atheists, Muslims and traditional Jews. The idea of the Trinity is hard to fathom, with God being three in one. “The word ‘trinity’ isn’t in the bible!” they say. They are right the Trinity isn’t in the bible but the concept is there if you dig deep enough.
In my bible study we were studying Mark and I came across this passage.
Mark 12:36 (New International Version)
David himself, speaking by the Holy Spirit, declared: “‘The Lord said to my Lord: “Sit at my right hand until I put your enemies under your feet.”‘
This is a copy of Psalm 110:1
Of David. A psalm. The LORD says to my lord: “Sit at my right hand until I make your enemies a footstool for your feet.”
The Lord speaks to the Lord! These are vitally important scriptures to give to someone with this question.
If you look at the Hebrew here:- (you can check yourself on biblehub.com)
לְדָוִ֗ד מִ֫זְמ֥וֹר נְאֻ֤ם יְהוָ֨ה ׀ לַֽאדֹנִ֗י שֵׁ֥ב לִֽימִינִ֑י עַד־ אָשִׁ֥ית אֹ֝יְבֶ֗יךָ הֲדֹ֣ם לְרַגְלֶֽיךָ׃
The letters in blue is Yahweh or Jahovah, the word for the God of Abraham, Isaac and Jaacob.
The letters in purple is Adonai, the actual word for ‘Lord’ in Hebrew.
So we know the doctrine of the Trinity is correct and exists in the Old and New Testaments. Another example of Jesus discretely mentioned before he arrives!
