That is so true, John.  It is so good to have someone to discuss these deep truths!  Love it!

Yes, we must be baptized into that body, or Holy City, by the same baptism which came on the Day of Pentecost.

Jesus Christ is that Holy City.  He is the head of it.  We are the body but members of the same City.  That is, the ones who have not rejected, but received, that Baptism of the Holy Ghost, not trying to reach the City some other way.

Jesus Christ is part of this BRIDE.  So who is that husband?

That City was certainly coming down when Jesus was baptized and when the disciples received the Holy Ghost.  See, Jesus also received the Holy Ghost when he was baptized!

What a pity that the church of our day has abolished this great truth and hidden it from the eyes of almost everyone!

thanks for this study.
