How many explicit statements do you want? There are so many that we could talk about that this thread would be 50 pages long and we wouldnt even scratch the surface. From the gospel of John:
No mere man can give someone eternal life. No mere man can say "I and the Father are one". Muhammed could NEVER say that he could give eternal life or that he and the Father are one.
But HOW did Jesus define His oneness with the Father? From John 17:20-23,
"Neither pray I for these [His Apostles] alone, but for them also which shall believe on me through their word;
That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.
And the glory which thou gavest me I have given them;
that they may be one, even as we are one:
I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me."
Christ clearly lays out that He explicitly wants His Apostles to be one even as He and the Father are one. If you believe in the trinity, then the only conclusion that can be drawn is that Christ is praying that the Apostles will all me somehow melded together into twelve separate, yet somehow still one whole, super Apostle. And then somehow that super Apostle would meld and become one with God, making God in fact 15 separate beings, yet only one being. After all that is how the trinity defines the relationship between God and Jesus. It makes no sense.
It is instead pretty obvious what Christ means. He is praying that the Apostles will be one as He and the Father are one, united in the cause of truth and salvation, that through the Spirit the Apostles will act together to lead the church, preach the gospel, and act in Christ's name. And this spiritual unity is the same unity Christ shares with the Father. They are perfectly united in all things, the Son having submitted Himself perfectly to the will of the Father, as we see in Gethsemane when Jesus prayed "not
my will but
thy will be done." (Luke 22:42) Christ and the Father even had individual, separate wills, yet Christ being in unity with teh Father, perfectly One with Him, submitted to the Father's will. And this is the power of Christ's Atonement for us, that it reconciles us to God and makes us One with Him, even as He and Christ are One, receiving all the glory the Son does as well. A beautiful truth, and an understandable one. God is not a "great mystery" completely incomprehensible to His children. Rather He is our Heavenly Father, the "Father of spirits" (Hebrews 12:7-9) who wishes us to come to Him, choose to follow Him by obeying the Gospel of Jesus Christ, and love one another.
