The meaning of the Sunday Mass Readings for May 2026 is made clearest by Catholic doctrine for “in the supremely wise arrangement of God, Sacred Tradition, Sacred Scripture and the Magisterium of the Church are so connected and associated that one of them cannot stand without the others” (CCC 95[1]). Let us connect May’s Readings[2] with Catechism of the Catholic Church to know the unchanging truth of Catholic doctrine we should take away from the Readings.
May 3, The Fifth Sunday of Easter
In the Second Reading, all the members of the Church are exhorted to be “a priesthood.” In the Catholic Church there are two priesthoods: the priesthood of the laity (the non-ordained) and the ministerial priesthood (the ordained). The priesthood of the laity means that “all the disciples of Christ . . . should present themselves as a living sacrifice, holy and pleasing to God. Everywhere on earth they must bear witness to Christ and give an answer to those who seek an account of that hope of eternal life which is in them” (Lumen Gentium 10 cited in CCC 1546). Catholics best bear witness to Christ when they explicitly share the truth of Catholic doctrine.
In today’s Gospel, Jesus tells His disciples that He is preparing a place for them in His Father’s house. “Left to its own natural powers humanity does not have access to the ‘Father’s house,’ to God’s life and happiness. Only Christ [through His atoning death on the cross] can open to man such access . . .” (CCC 661). Catholic morality, worship, and prayer provide the greatest happiness possible until the complete happiness only found in the Father’s house, which is the Kingdom of God.

May 10, Sixth Sunday of Easter
In the First Reading, the apostles in Jerusalem sent Peter and John to Samaritans who had been baptized but had not received the Holy Spirit. When Peter and John laid hands on them, they received the holy Spirit. “[T]he apostles, in fulfillment of Christ’s will, imparted to the newly baptized by the laying of hands the gift of the Spirit that completes the grace of Baptism. . . . The imposition of hands is rightly recognized by the Catholic tradition as the origin of the sacrament of Confirmation, which in a certain way perpetuates the grace of Pentecost in the Church” (CCC 1288).
Today’s Gospel tells us that the world neither sees nor knows the Holy Spirit. The Catechism teaches where to find the Holy Spirit: Sacred Scripture, Sacred Tradition, the Magisterium, the Sacraments, prayer, the charisms and ministries of the Church, the signs of apostolic and missionary life, and the witness of the saints (CCC 687-688) when they are in harmony with Catholic doctrine. Prayer, reflection on Scripture, or discernment that contradicts Catholic doctrine is not of the Holy Spirit. See CCC 737-741.

May 14, The Ascension of the Lord
The “historical and transcendent event of the Ascension” (CCC 660), reported in today’s First Reading and Gospel, is “the irreversible entry of [Jesus’] humanity into divine glory” (CCC 659). Jesus ascended into Heaven with the glorified body He had from the moment of His Resurrection. Jesus still has the glorified body He had at His Resurrection. Jesus has transcended space and time. So will all who enter God’s Kingdom.

May 23, Pentecost Sunday at the Vigil Mass

May 24, Pentecost Sunday Mass During the Day
The Catechism cites the First Reading and the Gospel Reading to teach: “On several occasions Christ promised this outpouring of the Spirit, a promise which he fulfilled first on Easter Sunday and then more strikingly at Pentecost” (CCC 1287).
An important takeaway from today’s Gospel is that the “saving mission entrusted by the Father to his incarnate Son was committed to the apostles and through them to their successors” (CCC 1120), who are the bishops. Unlike Protestant Christianity, but like Eastern Orthodox Christianity, Catholic Christianity has bishops who were ordained by bishops in an unbroken chain of ordination of bishops going back to the Twelve Apostles who ordained the first bishops. This reality is called Apostolic Succession. See CCC 77, 861, and 1087.

May 31, The Solemnity of the Most Holy Trinity
Today it is most appropriate to recall that the “mystery of the Most Holy Trinity is the central mystery of Christian faith and life.” “The whole history of salvation is identical with the history of the way and the means by which the one true God, Father, Son, and Holy Spirit, reveals himself to men” (CCC 234).
The meaning of God’s revelation to Moses, in the First Reading, is that “God’s very being is Truth and Love” (CCC 231). See CCC 215-217 for how God is truth. See CCC 218-221 for how God is love. “God himself is an eternal exchange of love, Father, Son, and Holy Spirit, and he has destined us to share in that exchange” (CCC 221).
The Second Reading, the source of the Greeting at Mass, shows “the revealed truth of the Holy Trinity has been at the very root of the Church’s living faith” (CCC 249). See CCC 232-267 for a greater understanding of the Trinity.
Today’s Gospel Reading is both supremely encouraging and supremely challenging. “By rejecting grace in this life, one already judges oneself, receives according to one’s works, and can even condemn oneself for all eternity by rejecting the Spirit of love” (CCC 679).
- From the First Reading (Exodus 34:4b-6, 8-9): Ex 34:5-6 is cited in CCC 210; Ex 34:6 in CCC 214, 231, and 2577; and Ex 34:9 in CCC 210.
- From the Second Reading (2 Corinthians 13:11-13): 2 Cor 13:13 is cited in CCC 249, 734, 1109, and 2627.
- From the Alleluia (Revelation 1:8): Rv 1:8 is cited in CCC 2854.
- From the Gospel (John 3:16-18): Jn 3:16 is cited in CCC 219, 444, 454, 458, and 706; Jn 3:17 in CCC 679; and Jn 3:18 in CCC 444, 454, and 679.
[1] CCC abbreviates Catechism of the Catholic Church. Any number after it is the number of a paragraph in the Catechism. For example, “CCC 95” means paragraph 95 of the Catechism.
[2] There are too many references in the Catechism to the verses in a month of Sunday Mass readings to cover all the pertinent doctrines. The bullet points allow you to explore further the Biblical basis of Catholic doctrine.
[3] If a Reading is not listed, then none of its verses is cited by the CCC.
