One of the main differences between our beliefs, is the LDS doctrine of a pre-existence where all mankind existed as spiritual creations or angles of God prior to being born into mortailty.
This doctrine has clear underpinnings in the Bible and was widely taught in early Christian Churches before Roman Emperors at the time of Constantine were awarded the ultimate authority of Christian Doctrine.
Please excuse me for believing in the same doctrine as 2nd Century Oridgen and other early Christian Theologians, which didn’t survive the Roman Emperor edits.
By thier and my interpretation, Satan is a errant spiritual brother to all of Gods children.
To a certain degree this is secondary to our belief, worship and faith in the God the Father and in the redeeming blood of Jesus Christ, the Savior.
Where you err, is that when God created man, he created him as a living soul. Angels do not have souls, therefore, we are not like them. If you get into the Word, you will find that angels have no part in redemption. They worship God, but when you read in Revelation about the saints worshiping Jesus for His salvation - the angels have to step back - they can’t partake in that particular part of our worship.
There is definitely a difference between angels and man because the Bible says that we were created a little lower than the angels. That doesn’t make us equal.
You seem to be coming down hard on Catholics which teach the Trinity. The term trinity isn’t in the Bible, but the word Godhead is - and it says that in Him (Jesus) dwelt the fullness of the Godhead -this is where we get the term trinity. The Catholics are correct in this belief.
