1 Tim. 3:14-16 (ESV)
I hope to come to you soon, but I am writing these things to you so that,  if I delay, you may know how one ought to behave in the household of God, which is the church of the living God, a pillar and buttress of truth.  Great indeed, we confess, is the mystery of godliness:
He was manifested in the flesh,
vindicated by the Spirit,
seen by angels,
proclaimed among the nations,
believed on in the world,
taken up in glory.
I for one am glad that Paul took the precaution of writing to Timothy regarding these things, as if he had met with Timothy face to face we would be missing quite a bit. I suppose there is a lot that Paul told Timothy aside from what is written here, but at least we have the important things here. I like the descriptions of the Church here, the household of God, the church of God, a pillar and buttress of truth. The truth is Christ, the gospel, the forgiveness of sins. This is what the church should be about, nothing else. Too often it becomes about other things. Most common to this is law, and law of the worst kind, made up human law that has nothing to do with what the Bible says, but only about the personal opinions and control of a megalomaniac.
But the mystery of godliness is Christ. He was manifested in the flesh, our flesh, flesh of our flesh and bone of our bone. He was vindicated by the Spirit when he rose from the dead. He is seen by angels not only in heaven, but in his body that is the church. Angels see Christ in us, even when we see nothing but sin. It is Christ that should be proclaimed among the nations, when too often he is neglected by the church. Yet He has been proclaimed among the nations and is even today. Godliness amidst the gentiles, who don’t have the laws of moses. He is believed on in this world, and is the only one worthy of our fear, love and trust in God. He is taken up in glory. Christ, Christ, Christ is the mystery of Godliness, for Godliness is attained only in him. Godliness is not found outside of Christ. It is not found in the law.
