Correct, while reading through some of the posts here, bingo, yours appeared, and you're correct. for it is the revealing of God in a flesh body, his temple. Daniel saw the Lord as the Spirit with a body in a vision, (compare Daniel 10:4-9 with Revelation 1:13-15, it's the same person in both visions), which is the key to the whole book of Revelation. the whole chapter 10 of Daniel is good for your edification.
as the Spirit, yes, the Holy Spirit, the almighty, the diverse one. notice Jesus is the one who address all 7 churches, but notice how each letter ends ..... the same, "He that hath an ear, let him hear what the Spirit saith unto the churches". he might address each one differently as stated, but each letter ends the same way. THIS IS THE GREAT "I AM", who is the head of the churches, his Spiritual body. in each letter he gives a warning of "The danger of Syncretism". his church, as a bride, she is to be without spot or wrinkle.
I don't have all the answer, but some of the post here I have heard before. and many post are good ones. but as said, "LET THE SPIRIT, THE HOLY SPIRIT GUIDE YOU.
hope this helped some.
