Any adult interested in becoming a Catholic is asked to participate in the R.C.I.A. The process begins when an inquirer presents himself or herself. Reception into the Church takes place when the person is ready. Those who are unbaptized will have a slightly longer process than those who are baptized into the Christian family. Sessions for inquirers and their sponsors are held on Sunday mornings. Those who are already Catholics who wish to renew their faith also may join the journey in many roles.
