This is one of the only ordinary time feast days in the entire liturgical calendar where three of the four readings tell the exact same prophesy. This is the case with the First reading, Responsorial Psalm, and the Gospel reading which all tell the story (or prophesy, really) of the vineyard of the Lord.
Generally, that kind of cohesion is reserved for the seasons of Advent, Lent, and Easter. But today the entire redemption story between God, his son Jesus, and his people is summarized so well in these readings.
Entrance Antiphon:
Within your will, O Lord, all things are established,
and there is none that can resist your will.
For you have made all things, the heaven and the earth,
and all that is held within the circle of heaven;
you are the Lord of all.
(Esther 4:17)
Psalm 80
The vineyard of the Lord is the house of Israel.
Communion Antiphon:
The Lord is good to those who hope in him,
to the soul that seeks him.
(Lamentations 3:25)
