Jesus and satan - Brothers?

One of the claims that Mormons make is that Jesus and satan are brothers. 

I find this claim interesting as I had never heard such a thing so when the idea was presented to me it was a completely foreign concept. My mind immediately balked at the idea as the first verse that popped into my head was a verse many Christians know quite well, John 3:16, "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life" (KJV). 

Some say that mormons don't believe satan is literally God's son, but that mormons believe that God is the father of all spirits, which comes from Hebrews 12:9, "Furthermore we have had fathers of our flesh which corrected us, and we gave them reverence: shall we not much rather be in subjection unto the Father of spirits, and live?" (KJV). In this sense, mormons believe that satan and Christ are brothers in the same sense that all men and women are siblings to satan. Though often also claim we are all sons and daughters of God so everyone is a brother and sister of each other, and so on and so forth. This is not actually biblically sound. 

When you are a brother or sister with someone under God it is through the Holy Spirit because you are adopted in to God's kingdom. How are you adopted into God's kingdom? By accepting Christ as your savior and through Christ being your brother, God ADOPTS you. This is backed up scripturally in several places, including Romans 8:15, "...but ye have received the Spirit of adoption, whereby we cry, Abba, Father" as well as Ephesians 1:5, "Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of His will," (KJV). If you were already His child, adopting you wouldn't make much sense now would it? When it is saying father in Hebrews, it is more referring to creator.

Also, satan was an angel, in Ezekiel 28:14-17, "Thou art the anointed cherub that coveter; and I have set thee so: thou wast upon the holy mountain of God; thou hast walked up and down in the midst of the stones of fire. Thou wast perfect in thy ways from the day that thou wast created, till iniquity was found in thee. By the multitude of thy merchandise they have filled the midst of thee with violence, and thou hast sinned: therefore I will cast thee as profane out of the mountain of God: and I will destroy thee, O covering cherub, from the midst of the stones of fire. Thine heart was lifted up because of thy beauty, thou hast corrupted thy wisdom by reason of thy brightness: I will cast thee to the ground, I will lay thee before kinds that they may behold thee."

Something interesting about satan being an angel is the fact that Christ actually created satan as it states in Colossians 1:12-17, "Giving thanks unto the Father, which hath made us meet to be partakers of the inheritance of the saints in light: Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son: in whom we have redemption through His blood, even the forgiveness of sins: Who is the image of the invisible God, the firstborn of every creature: For by Him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by Him, and for Him: and He is before all things, and by Him all things consist" (KJV).

And we can also see the angels were made, as Nehemiah 9:6 states, "Thou, even thou, art Lord alone; thou hast made heaven, the heaven of heavens, with all their host, the earth, and all things that are therein, the seas, and all that is therein, and thou preserves them all; and the host of heaven worshippeth thee" (KJV). Thusly, the angels were created and since satan was indeed an angel, then he was created through Christ. I would say the creations/origins of Christ and satan are biblically quite different and therefore, they are not brothers..
