Is Christianity one religion among many? Is it one way to peace and eternity amongst other options like Hinduism, Islam, New Age etc.? Jesus came to be the one and only means of salvation: the one way to the Father, the one truth and the one life (John 14:6). Christianity is the means by which people discover, encounter and share in the life-changing work that Christ did. No other religion, way or philosophy was determined by God to be a means of peace, joy and eternal life. The fullness of Christ is found in the Catholic Church. Catholicism is the fullness of Christianity; it is the fullness of the gifts God has given to His adopted children. 

RCIA is the Rite of Christian Initiation of Adults. It is a process that begins with evangelization, then a period of teaching, then a period of pray and study, the reception the Sacraments of Initiation (Baptism, Confirmation, Holy Communion) and Easter gatherings with the parish. RCIA can benefit anyone seeking one of these three Sacraments or all three: the unbaptized, non-Catholic Christians or Catholics in need of one of their Sacraments.
