A Christian that believe in one God and gives him no image. What kind of Christian is that?

That would make you Unorthodox, i.e., not pertaining to either Catholic or Protestant orthodox Christianity. Because God is Spirit, it is impossible to give Him any image. However, Trinitarian Christians acknowledge that there is only the One Being of God, but within the Godhead subsist the three persons of Father, Son and Holy Spirit. Not three Gods, however.

Orthodox Christians also believe that Jesus was more than just a man, a prophet. The Christian Bible tells us that before Jesus came to earth to be born and dwell with us, he was with God, in the beginning as the eternal and uncreated Word (or Logos) of God. The Christian Bible also tells us that Jesus died, was resurrected and returned to heaven from whence he came.

Looking at your profile, it seems likely that you are a Muslim. That might explain why you do not give God any image and why you believe that Jesus is only a man, a prophet from God. If I am wrong, I will apologise.

You may be an Iconoclast. The reason that there are so many pictures of God and Jesus and the Holy Spirit in Christian churches is because we believe that when the Second Person of the Trinity (Jesus) took on human flesh in the Incarnation that He made a real "Image" of himself in human history. Therefore depictions of Him are licit because He made a depiction of Himself.

Iconoclasm was an overreaction to image worshipping which resulted in the smashing of all depictions of God (Father, Son and Holy Spirit) and all other holy pictures, even relics of the saints.

There's no real sect you can join to be with your iconsclastic brothers and sisters (and any attempt to practice what they preach would hopefully be against hate crime laws). Catholics, Orthodox and most Protestants are not Iconoclasts, although Protestants are probably closest.

• Catholics pretty much embrace every tasteful depiction of God,
• Orthodox prefer icons and
• Protestants pretty much loath everything except smiling or knocking pictures of Jesus as Papist nonsense. But they like relics less than iconoclasts because they don't believe in the Communion of Saints in the same way Catholics and Orthodox do.

Basically, iconoclasm, wasn't necessarily about a hatred for art, but an exaggerated reaction against the doctrine that allowed the production of the art (i.e. the Incarnation). The Incarnation is central to all Christianity (and by extension all human history) so it's probably worth finding out what it is and why it's important before defining what kind of Christian believes the things you're asking about.

Virtually all Christians consider Jesus to be the image of God because of this passage in Colossians 1:15-16

The Son is the image of the invisible God, the firstborn over all creation. For in him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things have been created through him and for him.

If you are concerned with the question of whether Jesus is actually God, rather than whether he is merely the image of God, then the word you are looking for is probably 'Unitarian'. Unitarians believe that Jesus is the best and ultimate prophet and messenger of God, but not actually God. There are other kinds of groups too, including 'Christadelphians'. If you want more specific information you would have to tell us more about what you believe. Unitarians and Christadelphians consider Jesus to be the image of God, for the reasons I said above.

If your Catholic priest never said at any time that Jesus Christ is God, then he either presumed you already knew that or, if you were of a different faith, didn't want to offend you by contradicting your faith. He almost certainly believed it himself.
