Marriage

So husbands ought to love their own wives as their own bodies… For we are members of His body, of His flesh and of His bones. “For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh.” This is a great mystery, but I speak concerning Christ and the church. 

– Apostle Paul, Eph 5:28–32 (NKJV)

And Jesus answered and said to them, “Have you not read that He who made them at the beginning ‘made them male and female,’ and said, ‘For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh’?’

– Jesus Christ, Matthew 19:4–5 (NKJV)
