“But the hour is coming, and now is, when the true worshipers will worship the Father in spirit and truth, for such the Father seeks to worship him. God is spirit, and those who worship him must worship in spirit and truth.” (John 4:23-24)

I want the truth, the whole truth and nothing but the truth …. 

You owe it to yourself to learn all about Christ’s life and teaching and what the Church believes. The goal is exposure to the entire content of the faith—not just a few things sprinkled willy-nilly. It ultimately boils down to truth, and truth matters!

The Catholic Online School RCIA program is carefully designed to provide you with a systematic, comprehensive education in the divine faith of the Church. The goal is to make you “of the truth” by exposing you to the voice of Christ.

In this second section of the program, we explore “The Celebration of the Christian Mystery.”

In this section, we learn about the second pillar of the faith as it’s presented in the Catechism of the Catholic Church. Here are some of the topics you’ll learn about:

  •  The liturgy of the Church and the holy sacrifice of the Mass
  • The sacraments of initiation and the sacraments at service to communion
  • Christian funerals
  • Sacramentals, blessings, and popular devotions
  • Major and minor exorcisms
  • The Holy Rosary


From all of us at Catholic Online School: May Christ bless you on your journey of faith.

“The Celebration of the Christian Mystery" is broken up into 5 different chapters. 

In this course, students will work through Chapter 5.

Students will cover - 

  • Course 10 - Additional Liturgical Celebrations and Devotions


Earning a certificate of completion in this online course is not a substitute for completing a parish-based RCIA program. The Sacraments of Initiation can only be conferred by a bishop or priest. This certificate means you have successfully completed a course of study that is intended to supplement your parish RCIA program.
