Less happy for me is when I see Christians from other traditions being received into the Roman Catholic Church at the Easter Vigil. I need to explain this. I am myself a convert to Roman Catholicism - I've described this transition to Rome elsewhere - so I'm obviously not opposed to the idea of non-Catholic Christians becoming Roman Catholics. What I object to, rather, is receiving these Christians into the Church at the Easter Vigil.
In the history of Christianity, the Easter Vigil was traditionally the time when catechumens were baptized after a long period of preparation. Those who had not experienced new birth through water and the Spirit experience that new birth at the Easter Vigil as we celebrate the renewal of life in and through the resurrection of Jesus Christ.
In recent decades, those catechumens went through a process of catechesis known as RCIA - Rite of Christian Initiation for Adults. Unfortunately, Christians already baptized in non-Catholic traditions who wish to become Roman Catholics have been asked to go through RCIA themselves, this despite the fact that RCIA was developed specifically for those with little to no exposure to Christian history and theology, and not for those who were practicing members of their own non-Catholic traditions. With non-Catholic Christians and catechumens taking RCIA together, the Easter Vigil has become a time when both catechumens are baptized and non-Catholic Christians are received.
None of this is in accord with the National Statutes of the Catechumenate, approved by the United States Conference of Catholic Bishops in 1986. The statutes can be found in Appendix III of the RCIA ritual book, and they can also be found here. The key statutes are nos. 30-33, and I've pasted them below:
