Eph. 5:25-27 
Husbands, love your wives, even as Christ also loved the church, and gave himself for it; [26] That he might sanctify and cleanse it with the washing of water by the word, [27] That he might present it to himself a glorious church, not having spot, or wrinkle, or any such thing; but that it should be holy and without blemish. 

Eph. 5:32 
This is a great mystery: but I speak concerning Christ and the church.
