From the Gospel according to Mark 3:31-35

The mother of Jesus and his brothers arrived at the house.Standing outside, they sent word to Jesus and called him.A crowd seated around him told him,“Your mother and your brothers and your sistersare outside asking for you.”But he said to them in reply,“Who are my mother and my brothers?”And looking around at those seated in the circle he said,“Here are my mother and my brothers.For whoever does the will of Godis my brother and sister and mother.

The Gospel of the Lord.

Beyond Words.

Jesus establishes a new way of being family, and it is through fulfilling His Will. How wonderful it is that there is a new path to becoming part of God’s family. Bonds that unite us far more strongly than those of blood.
What a treasure to experience this strong union that the Lord establishes with Him and among us.

Applied to Married Life:

Joe: There is a way to unite us that is stronger than the flesh, and it is the union in the Lord. Since we’ve drawn closer to Him, I feel a much deeper bond with you.
Sofia: Absolutely. It happens between us, with our children, and with our brothers and sisters in faith.
Joe:Even in our marital intimacy, there’s a deeper unity when we live it with chastity and when spiritual union occurs at the same time.
Sofia: A union experience unknown to those consumed by lust, as Saint John Paul II says. Truly a treasure.
Jose: It’s beyond Words.

Mother,

How wonderful to call you Mother, how marvelous to call God Father, and what a blessing to be betrothed to Your Son. Praise be to God who makes us so completely His own.
