Shout for joy, O daughter Zion!
The Lord, your God is in your midst;
he will rejoice over you with gladness,
and renew you in his love,
he will sing joyfully because of you!
In the Hebrew scriptures, God almost always refers to himself with masculine imagery—father, husband)—but his people (and later the Church) are sometimes describes as his children, his son, and—especially when Zion is spoken of—his daughter. Gaudete Sunday isn't just a day for us to rejoice in God, but when we realize he rejoices over us as a father does over his beloved daughter.
