1 Timothy 3:15-16

v. 15 but in case I am delayed, I write so that you will know how one ought to conduct himself in the household of God, which is the church of the living God, the pillar and support of the truth.

I often quote the bold part of the verse a lot. I just like it. It's an integral role the Church plays in the world.
It's also interesting to me that God in the Holy Spirit dwells in our bodies as his temple (1 Cor. 6:19) yet also in the Church as corporate believers meeting together. Eastern Orthodox folks would point to this verse as evidence that God inhabits a physical building. But, I think Paul is saying "how one ought to conduct himself in the household of God, which is made up of the church of the living God [ie: the individuals (temples) together]."

v. 16 By common confession, great is the mystery of godliness: He who was revealed in the flesh, Was vindicated in the Spirit, Seen by angels, Proclaimed among the nations, Believed on in the world, Taken up in glory.

One of the earliest church creeds that we have. What does "vindicated in the Spirit" mean or refer to? I think the creed is clearly chronological of his life, burial, resurrection, ascension. What's the significance of "seen by angels"? I think it's referring to his post-burial, when the angels proclaimed to the women at the tomb: "He is not here, for He is risen." May it also be a reference to 1 Peter 3:19?
