In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God; all things were made through him, and without him was not anything made that was made. In him was life, and the life was the light of men. (John 1:1-4)

We are made in and through and with Christ—the life and light of men. As St. Leo the Great said in the 5th century in speaking of the sacrament of Baptism, which makes us Christians and members of Christ’s body, “Never forget that you have been rescued from the power of darkness and brought into the light of the Kingdom of God.”

The truth is, we desperately need Christ our Lord whose life and love rescues us from the power of darkness; therefore, it’s essential that we live our life in him.

But what does it mean to live one’s life in Christ? How is it possible? And why is it essential to do so?

In this section of the program, titled “Life in Christ,” we explore and answer those questions and more.

In this series of lessons, you’ll learn about the third pillar of the faith as it’s presented in the Catechism of the Catholic Church. Here are some of the topics covered:

  • The dignity of the human person, the gift of freedom, and the call to Beatitude
  • The reality of sin, the three sources of morality, and the human conscience
  • The cardinal and theological virtues
  • The social justice doctrine of the Church
  • The moral law, grace, and justification
  • The Church as mother and teacher
  • An in-depth exploration of the Church’s teaching on the ten commandments


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


“Life in Christ" is broken up into different chapters. 

In this course, students will work through Chapter 5.

Students will cover -
