Today is the liturgical memorial of St. John XXIII. This is the first time the universal Church is permitted to observe this feast. He was the beloved Servant of the Servants of God.

Here is the opening prayer for the Novus Ordo Liturgy.

Almighty and eternal God, who in the Pope, Saint John XXIII, gave to the whole world the shining example of a good shepherd, grant that, through his intercession, we may with joy spread abroad the fullness of Christian charity.

Through our Lord Jesus Christ, your Son, who lives and reigns with you in the unity of the Holy Spirit, one God, for ever and ever.
