“For this reason a man shall leave his father and mother and cleave to his wife, and the two shall become one flesh. This is a great mystery, but I speak concerning Christ and the Church. Nevertheless, let each one of you in particular love his own wife as himself, and let the wife see that she respects her husband.“ — Ephesians 5:31-33
What a high calling marriage is! The first command God gives to man following the creation of woman is to leave mother and father and cleave to his wife (Genesis 2:24). Adam did not have earthly parents, which makes this scripture, written in the beginning, even more extraordinary and weighty.
Paul, the writer of Ephesians, repeats this statute in the New Testament, calling it a great mystery and comparing the marriage relationship to Christ and the Church. Each marriage is a “First Family.”
“So then you are no longer strangers and aliens, but you are citizens with the saints and also members of the household of God, with Christ Jesus himself as our Cornerstone. In him the whole structure is joined together and grows into a holy temple in the Lord; in whom you also are built together spiritually into a dwelling place for God. (Ephesians 2:19)
This is marriage.
This is the Church.
