The aim of this explanation is to simply show that John 20:28 is in no way a verse which supports the man made doctrine known as the ‘trinity’ – therefore it does not state that Christ is G-d.
Instead we will see that just as the King Messiah (Christ) quoted the Psalm ‘My God, my God, why have you forsaken me…’ (Psalm 22:1) out of reverence to the Scriptures – so to does righteous Thomas quote a Psalm to Christ, giving thanks to G-d also – as we are instructed to do out of love for the word;
‘speaking to one another with psalms…’
(Ephesians 5:19 NIV)
Such conduct and reverence of God’s Holy Scriptures are a pleasing thing to God and worshipful to Him Who is above all.
Thomas said to him, “My Lord and my God!”
John 20:28 NIV
Even the sparrow finds a home, and the swallow a nest for herself, where she may lay her young, at your altars, O LORD of hosts, my King and my God.
Psalm 84:3 ESV
John 20:28 – ‘lord’ is the Strong’s Concordance word G2962
Definition: lord, master
Further, the HELPS Word Study here seems to agree here stating along the lines that, the word can speak of a person in absolute control; a King could certainly be seen as such in a land.
Hoping it is fruitful.
Shalom and kind regards,
May the Holy G-d bless you beyond maximum, believing in His risen Son the Lord Jesus Christ (Adonai Yehoshua HaMoshiach). Amen.
