Charles Spurgeon Commentary Ephesians 5:31-32

"For this cause shall a man leave his father and mother, and shall cleave to his wife; and the two shall become one flesh. This mystery is great: but I speak in regard of Christ and of the church." — Ephesians 5:31-32 (ASV)

There is the mystery, that he should leave his Father, and quit the home above, and become one flesh with his elect, going with them, and for their sakes, through poverty, and pain, and shame, and death. This is a marvel and a mystery indeed.
