Some Basic Suggestions: Note: Scripture passages below contained within red, rounded brackets (…) indicate a reference from today’s readings in whole or in part.
First, Psalm & Gospel Readings: God, because He is good/merciful (Ps 89:2-3) will bless those who exercise goodness/mercy by aiding the prophetic mission of the Church (2 Kings 4;14-16; Mt 10:40-42). Therefore, we ought to provide aid as the woman of Shunem did (2 Kings 4:9-10) and as Christ recommends (Mt 10:40-42).
Second Reading: Baptism. See CCC 1213-1284. One could especially focus on the following: (A) Baptism establishes communion with our Lord’s Death and Resurrection (Rom 6:3-4); [CCC 1227; cf. 790]. (B) Baptism effects the grace to live in newness of life (Rom 6:4, 8-11); [CCC 1265-1266] Here it should be noted that “live in newness of life” is not primarily a reference to our future resurrection (though this is implied), rather, It is a reference to living in new life now, free from the old life of sin (Rom 6:1-2, 6-19). In the context of Romans it is emphasized that this new life is lived in the Spirit (Rom 8:1-2, 8-11, 13). See also Gal 5:16-24; CCC 736). (C) The baptized have an obligation to support the apostolic mission of the Church (CCC 1270). This last point provides a connection with the first and gospel readings.
