A childhood belief about hymns

In a Presbyterian sunday school at the age of 8 or 9, I learned a hymn whose lyrics went:

[i]The Church's one foundation is Jesus Christ, our Lord.
She is the true creation of water and the Word.
From Heaven he came and sought her to be his holy bride.
With his own blood he bought her, and for her life he died.[/i]

The doctrines proposed in this text were rather unlike anything I had heard before. I gathered that Jesus was married, even if Jesus' wife's name was not preserved by history. Jesus came down from Heaven to marry her. Jesus' wife was created from water, no doubt by a process similar to Eve's creation from Adam's rib. Jesus' watery wife did something bad that Jesus took the rap for when he was crucified.
