I ask this because when I read about the attributes of Jesus in the Trinity and compare him to the Jesus as explained by Mormon doctrine I find very little difference. With that being said if there are differences, how do they effect his divinity?
The answer to this, in regards to Jesus Christ's divinity, would be: There is little to no difference. The differences in Mormon theology do not alter the way Christ's Divinity is regarded by Mormons vs. the regard given by Trinitarians. Trinitarians and Mormons both view Christ as Divine, and the Most Divine Possible.
I will provide some background, and also explain one potentially insignificant perceived difference that comes to my mind.
While the Mormon Church may believe that the Trinity are 3 separate beings with the same purpose, as opposed to 3 forms of the same being (possibly an oversimplification, but the Trinity is difficult for me to explain) The role of Jesus Christ is the same, through him and him alone comes Salvation. He is Divine. He is God. (From of Mormon perspective you might alter that to say, he is "a God") It it through his merits that all mankind may be saved and live Happily in the afterlife (slightly different perspective on afterlife for Mormons and Mainstream Christinity)
One specific attribute that may be a little (or a lot) different, is the existence of Jesus Christ's physical body. Mormons Believe he still has one, a Divine immortal body that is inseparable from his spirit. Mainstream Christian religious belief may not agree with this idea. I've met pastors who have said that Christ only took a physical form while on earth, and once ascended to heaven returned to a spirit, or spiritual form, and that we too will be like that while in Heaven.
Mormons believe the physical form and spiritual form together will be the final Divine form. Not a mortal physical body, but an immortal physical body. Mormons will refer to this body as a Celestial, Perfected or a Glorified Body. You'd find information about this in The Doctrine and Covenants, a publication from the LDS Church. It's also been repeated by LDS Apostles and Prophets throughout the years.
The difference in Mainstream Christian or more specifically Trinitarian beliefs vs. Mormon beliefs on Christ's Divine physical form may be the biggest difference, if and when it's a difference at all.
The following link may suggest that the difference I perceive is not really a difference: Jesus Ressurection Was Physical
Here is an Official LDS statement on who Jesus Christ is, and his Divine purpose: The Living Christ
There are a couple significant differences between Jesus Latter Day Saints(LDS) believe in and Jesus Christ we see in the Bible.
The Differences are as follows, I would just give some Bible references which I think should disprove these beliefs
They believe Jesus is Son of God in the same way as you and I - this means that they assume that Jesus is every Human's Spirit Brother
They believe Jesus is a Creation of God
They also believe Lucifer(The Devil is a Brother of Jesus)
They believe Christ atoned on the Cross and also in the Garden of Gethsemane
