The Bridal Chamber

"The Lord [did] everything in a mystery, a baptism and a chrism and a eucharist and a redemption and a bridal chamber." (The Gospel of Philip 67:28-30-Nag Hammadi Library)

"Baptism is 'the Holy' building. Redemption is 'the Holy of the Holy.' 'The Holy of the Holies' is the bridal chamber." (The Gospel of Philip 69:22-25)

The writer of the Gospel of Philip, one of the apocrypal documents in the Nag Hammadi library, believed that the most sacred part of the temple was what he called the "bridal chamber," where a "woman is united to her husband" and "will no longer be separated." If a person does not receive these blessings in this world, he asserted they cannot be received elsewhere.(Gospel of Philip 69:14-25; 70:17-20; 86:3-7; see R. McL. Wilson, trans., The Gospel of Philip (New York: Harper & Row, 1962), 45-46,62.

Compare D&C 132:15-18:

15 Therefore, if a man marry him a wife in the world, and he marry her not by me nor by my word, and he covenant with her so long as he is in the world and she with him, their covenant and marriage are not of force when they are dead, and when they are out of the world; therefore, they are not bound by any law when they are out of the world.
16 Therefore, when they are out of the world they neither marry nor are given in marriage; but are appointed angels in heaven, which angels are ministering servants, to minister for those who are worthy of a far more, and an exceeding, and an eternal weight of glory.
17 For these angels did not abide my law; therefore, they cannot be enlarged, but remain separately and singly, without exaltation, in their saved condition, to all eternity; and from henceforth are not gods, but are angels of God forever and ever.
18 And again, verily I say unto you, if a man marry a wife, and make a covenant with her for time and for all eternity, if that covenant is not by me or by my word, which is my law, and is not sealed by the Holy Spirit of promise, through him whom I have anointed and appointed unto this power, then it is not valid neither of force when they are out of the world, because they are not joined by me, saith the Lord, neither by my word; when they are out of the world it cannot be received there, because the angels and the gods are appointed there, by whom they cannot pass; they cannot, therefore, inherit my glory; for my house is a house of order, saith the Lord God.
