........If I can’t find sufficient evidence to support the Trinity then I can’t accept it as being true. I would have to remain neutral about it and chalk it up as something I cannot believe in or teach to others if I cannot support it with the scriptures.
If you can't find sufficient evidence to support the Trinity - you just don't want to find it. The evidence does not depend on John 1 not saying "a" God. John 1 could say "a" God and the Trinity would still be all over the scriptures.
........Luckily I still believe that John 1:3 and One God are both very strong evidence.
Darn tootin.
........I’m just surprised that so far I’m unable to find anything conclusive that openly states Jesus is God in the Greek text.
There are lots of them not the least of which is ""Be on guard for yourselves and for all the flock, among which the Holy Spirit has made you overseers, to shepherd the church of God
which He purchased with His own blood."
Just because the Greek word θεός, οῦ, ὁ θεός, οῦ, ὁ (#2316 in Strong's concordance) can be translated either "God" or "a God" hardly negates the scriptural evidence for the Trinity.
The same θεός, οῦ, ὁ θεός, οῦ, ὁ can be noted in virtually all of the references to God in the New Testament. Dozens of examples could be put forth to show the ridiculous nature of doing what the JW's do. But the idea of θεός, οῦ, ὁ θεός, οῦ, ὁ as found all over the book of Colossians should suffice.
"He is the image of the invisible God." (Col. 1:15) What? Is He the image of Himself or the Father? Is He the image of just any old God among billions of Gods or the One True God of the O.T.?
If we applied "a" God to all Strong's #2316 Greek words in the N.T. we'd have a never ending number of eternally existent Gods and we'd all be Mormons.
By the way - with
θεός, οῦ, ὁ θεός, οῦ, ὁ as your witness - are you perchance J.W. or Mormon?
Regardless of what you imply in the OP - you seem to be arguing for the legitimacy of their position more than simply looking for corroboration on the doctrine of the Trinity as you say.
I'm pretty sure I'm not the only one wondering about this.
If one has enough familiarity with this forum he will hardly be naive when it comes to this kind of duplicity.
