One of the great things about a good, Biblical confession of faith is that it underscores the unity of a body of Christian people, confessing the one Lord, one faith, with one mouth. It should reflect the fact that the Lord does not liken the church (if I may speak anachronistically) to a pool table, where individual balls roll around in myriad different directions at the same time, only occasionally bouncing off one another. Rather, He likens the church to a body, featuring both diversity and unity (1 Corinthians 12:12).
Having said that....
Reading through John in Greek I noticed something not obvious in modern English translations.
This man [Nicodemus] came to Jesus by night and said to him, "Rabbi, we know that you are a teacher come from God, for no one can do these signs that you do unless God is with him." 3 Jesus answered him, "Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God" (John 3:2-3)Nicodemus says "we know." Jesus replies, "Truly, truly I say to you," σοι (soi), the second person singular pronoun. Nic says "we"; Jesus says "thee." Jesus will not allow Nicodemus to hide amongst a crowd. He singles Nicodemus out, and deals with his soul, one on one.
Nor is this the only time that Jesus will in effect turn a "we" into "thee."
After this many of his disciples turned back and no longer walked with him. 67 So Jesus said to the Twelve, "Do you want to go away as well?" 68 Simon Peter answered him, "Lord, to whom shall we go? You have the words of eternal life, 69 and we have believed, and have come to know, that you are the Holy One of God." 70 Jesus answered them, "Did I not choose you, the Twelve? And yet one of you is a devil." 71 He spoke of Judas the son of Simon Iscariot, for he, one of the Twelve, was going to betray him. (John 6:66-71)Peter says "We have believed, and we have come to know." Jesus says, in effect, "Oh? One of that 'we' is a traitor, Peter. One member of the consensus from which you're drawing such comfort and strength is a devil. So what if your 'we' turns into 'me,' Peter? What then? Where will you stand, if you find yourself standing alone?"
So while I find much help, encouragement, and instruction in the great confessions, I have to remember: Satan may sift the body of which I am a part. I may find myself alone. Will I be able to say "I believe, and I have come to know"?
And when I stand before the throne, in one sense I surely will be alone. Then it won't be a question of what "we" believed, confessed, did, or were. The first person singular pronoun will predominate. I had better be able to say that
whatever gain I had, I counted as loss for the sake of Christ. 8 Indeed, I count everything as loss because of the surpassing worth of knowing Christ Jesus my Lord. For his sake I have suffered the loss of all things and count them as rubbish, in order that I may gain Christ 9 and be found in him, not having a righteousness of my own that comes from the law, but that which comes through faith in Christ, the righteousness from God that depends on faith-- 10 that I may know him and the power of his resurrection, and may share his sufferings, becoming like him in his death, 11 that by any means possible I may attain the resurrection from the dead (Philippians 3:7-11)
