How do you join the Catholic Church?
Rite of Christian Initiation of Adults
The Rite of Christian Initiation of Adults (RCIA), or Ordo Initiationis Christianae Adultorum (OICA) is a process developed by the Catholic Church for prospective converts to Catholicism who are above the age of infant baptism. Candidates are gradually introduced to aspects of Catholic beliefs and practices.  The basic process applies to adults and older children, with younger children initiated through an adapted version sometimes incorrectly referred to as the Rite of Christian Initiation of Children (RCIC)
