(Rite of Christian

Initiation of Adults)

The Rite of Christian Initiation of Adults (RCIA), or Ordo Initiationis Christianae Adultorum 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.

Roughly 8 months
The process of entering the Church (through RCIA) is designed as a multi-year process, but is often run as a roughly 8 month course, starting in late August or Early September and ending at the Vigil service on Easter.
Toward the end of the period, the Church continues the custom of "handing over" to the Elect the Creed (the summary of our faith) and the Lord's Prayer (which represents its practice of continuing prayer after the command of Jesus who taught us to pray).

The Catholic Church requires a dispensation for mixed marriages. The Catholic party's ordinary (typically a bishop) has the authority to grant them. The baptized non-Catholic partner does not have to convert.  The non-Catholic partner must be made "truly aware" of the meaning of the Catholic party's promise.
