ISB ~ Acts 2 v42

teaching … fellowship … bread … prayers:Essential actions of the Church’s life shown forth in the believing community of Jerusalem. They held to the doctrinal catechesis of the apostles (teaching), interpersonal communion and support (fellowship), the celebration of the Eucharist (breaking of bread), and community praise and petitions (prayers). Thus, in every aspect of life, the earliest believers were united as a family: they learned together, lived together, ate together, worshiped together, and prayed together (CCC 950, 1329, 2624).
