You posted the word 'trinity' is in the Book of Matthew. ( It isn't, FYI )
There are so many scriptures the apostles wrote regarding Jesus' ascension back to heaven that support the fact
there is no trinity and even before...Jehovah God and Jesus Christ are 2 separate beings...here are but a few...
Jesus approached and spoke to them, saying:
“All authority has been given me in heaven and on the earth." Matthew 28:18
"But he, being full of holy spirit, gazed into heaven and caught sight of God’s glory and of
Jesus standing at God’s right hand" Acts 7:55
"For he must rule as king
until God has put all enemies under his feet." 1 Corinthians 15:25
"which he exercised toward Christ
when he raised him up from the dead and seated him at his right hand in the heavenly places, far above every government and authority and power and lordship and every name that is named, not only in this system of things but also in that to come." Ephesians 1:20,21
"For this very reason,
God exalted him to a superior position and kindly gave him the name that is above every other name, so that in the name of Jesus every knee should bend—of those in heaven and those on earth and those under the ground" Philippians 2:9,10
But
when he again brings his Firstborn into the inhabited earth, he says: “And
let all of God’s angels do obeisance to him.” Hebrews 1:6
"Jesus approached and spoke to them, saying: “All authority has been given me in heaven and on the earth.
"But this man offered one sacrifice for sins for all time and
sat down at the right hand of God," Hebrews 10:12
"
He is at God’s right hand, for he went to heaven, and angels and authorities and powers
were made subject to him." 1 Peter 3:22
