“And He is the image of the invisible God, the firstborn of all creation. For by Him all things were created, both in the heavens and on earth, visible and invisible, whether thrones or dominions or rulers or authorities — all things have been created by Him and for Him. And He is before all things, and in Him all things hold together.
First, "The image of the invisible God". That means when you look at Him, you look at God. Notice as well that it says "firstborn", NOT first created. In the culture of the day, "firstborn" refers to rank, not physically being born first. Remember that David was the youngest of his brothers, but God said in Psalms that He would make David the firstborn. It's a rank. Then, of course, you have to blatantly say the Scriptures don't mean what they explicitly say when they say ALL THINGS were created by Him. Not all things "except Himself", all things. Also, you have to deal with Him being BEFORE all things. The only way you can make that say something different is if you add what isn't there, namely, "except Himself". If you accept Scripture as it is written and in the context of the time and culture it was written, the ONLY conclusion you can draw is that it is saying Yeshua is God.
Remember what I posted earlier, where I showed that Yeshua is seen leading the armies of heaven, bearing the name "The Word of God", and the title, "Lord of lords"? Are you ignoring that part, or did they just not teach you how to twist or downplay it?
