"Each year, on Holy Saturday during the Easter Vigil, thousands are baptized into the Catholic Church in the United States. Parishes welcome these new Catholics through the Order of Christian Initiation of Adults." (from the USCCB-United States Conference of Catholic Bishops)
Christian Initiation is accomplished through three sacraments: Baptism, which is the beginning of a new life; Confirmation, which strengthens and deepens that life; and Eucharist, Holy Communion, which nourishes the disciple with Christ's Body and Blood for a transformation in Christ.
