Just like with the rest of Mormon doctrine, these quotes from various people and times are contradictory https://www.mrm.org/christianity-quotes
Again, your Christ is not mine. Mine is one essence with the Father and the Spirit, not one of three separate beings (and also an entirely created being himself). The Father does not have a body of flesh and bones. He is not Elohim, a man born on another planet who eventually became a god himself by obeying the god of that planet. All of this is entirely foreign to the biblical faith. You've been ensnared in a belief system that would have you believe that the Apostles and Christ taught the things you believe today, but you couldn't be more wrong.
Sit down and read the entire Bible for yourself without the lens of Mormon doctrine. Read a modern translation like the ESV or LSB. Have you done that? Seek to understand it with fresh eyes as if you were a new convert who is eager to learn what the Word says.
Christ created everything, not only this world. Literally everything that exists was made by Him and is sustained by Him. He didn't organize pre-existent matter.
You need to escape from the false religion you are ensnared in and come to the true Christ, who is the only Christ that can save you. Your best efforts before God merit you absolutely nothing having to do with salvation or forgiveness of sins of any kind. You must trust wholly in the cross and the imputed righteousness of Jesus as the basis of your peace with God.
He kept God's law perfectly. You can't. He suffered the wrath of God in the place of sinners, taking upon Himself their penalty. The true gospel is that by trusting in Christ and what He has done, sinners can have peace with God forever. No mixture of my effort and God's grace (UNmerited favor) will grant me peace with a thrice holy God.
Are you the blessed man of Romans 4:8 to whom the Lord will not take your sins into account? Or is it the case that your sins will be imputed to you if you fail to deny yourself of ALL ungodliness. How are you doing?
D&C 82:7; “And now, verily I say unto you, I, the Lord, will not lay any sin to your charge; go your ways and sin no more; but unto that soul who sinneth shall the former sins return, saith the Lord your God.”
Isaiah 43:25; “I, even I, am he that blotteth out thy transgressions for mine own sake, and will not remember thy sins.”
God promises to not remember the sins of those who trust in the true Jesus. The false Jesus of Mormonism will forget them temporally, but then lay them back on your shoulders if you stumble in your walk with Him.
"The Nicean Creed that says all three are in one has no precedence in the Bible."
The Trinity is a biblical doctrine first and foremost. 1. Scripture teachers there is one God who created all things and has always been God. 2. Scripture teaches the Father is God, the Son is God, the Spirit is God. 3. Scripture teaches the Father is not the Son, the Son is not the Father, the Spirit is not the Father or the Son. Because of those three truths, I believe the the doctrine of the Trinity.
