I just asked him to expound..If he can't, he should just say so.
I don't think I should have to. Pretty much everyone in Western Society has heard these claims. But if you want to have some proof of why people believe that Here is a bible passage you may or may not know.
1 In the beginning was the Word, and the Word was with God, and the Word was God.
2 He was with God in the beginning.
3 Through him all things were made; without him nothing was made that has been made.
12 Yet to all who received him, to those who believed in his name, he gave the right to become children of God--
13 children born not of natural descent, nor of human decision or a husband's will, but born of God.
14 The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the One and Only, who came from the Father, full of grace and truth.
Essentially, The Word Was God, and the Word became flesh and lived among us, The one who came from the father.
Another Important one that also displays reasoning to believe this:
-Unto the Son He saith, Thy throne, O God, is for ever and ever.
God said to his son God your throne is forever (why would god call his son god?)
Emmanuel, God with Us
Matt 1:23 Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel,
Emmanuel interpreted is actually God with Us.
And so on and so forth over the course of the Old testament, and New Testament. Even the following are used interchangably between God and Jesus.
The Light, The Alpha and Omega, Logos (the Word), Lord.
The old Apostles Creed which is spoken to God, uses the phrases the Lord, Lord Father, Lord God, with the holy spirit refrenced as just a spirit. While the newer Nicene Creed spoken to Jesus is Lord Jesus, God from God, True God of God, Lord, with the holy spirit referenced as giver of life.)
(note newer and older are kind of relative, as the Apostles Creed was penned largely by Matthew in 28:19 although changed over time during the first and second century when it was finally put into writing. The Nicene Creed came shortly after the council of Nicea in which the Catholic Church was born, and thus the love affair with Jesus being the God of God, and immortalizing him began.
Its all there if you read the bible to be quite honest, most people skip that stuff, I luckily happened to read the greatest novel ever written. (It is really a great book, lots of murder, and infighting and all that good stuff) Jesus may or may not have been just a man, he may or may not have been god in the flesh, but there is writtng that both supports and refutes either claim within the bible itself. There are some who practice both ways.
Was that expanded enough for you or would you like more passages to look up, and other names that are interchangeable throughout out the texts. (Just for clarification to support my overall point that Christianity is just an evolved for of the old pagan religions primarily Egyptian. Horus was also referred to as the God of God, the Sun of God, the Light, the light of the word, the lamb of god, emmanuel, The Alpha and Omega, True God of God, etc etc. as was Judaism and as such is Muslim an evolved form of all three.)
