The Luke E. Hart Series is a Set of 30 Lessons that deal with matters of Catholic Belief, Tradition, Practice and Every Day issues. Each Lesson includes the PDF Booklet as well as the Podcast of the Book.
Lesson 11 ~ 20: How Catholics Worship
Introduction to Catholic Liturgy: Lesson 11

The sacred Liturgy is not just the Mass, but the Mass is the Liturgy with which most Catholics are familiar. Often, it is such a regular part of life that the simple and fundamental questions are overlooked. What exactly is a Liturgy? Why do we do it? We’ll survey the different answers that have been given to just what Liturgy is, learn the Church’s teaching, and develop our understanding of this basic activity of the Church.
Baptism and Confirmation: Lesson 13
The source and summit of the Christian life, the sacramental center for Catholics, is the holy Eucharist. Like Christ, the holy Eucharist is controversial and divisive. When Jesus initially taught crowds of people about the holy Eucharist, many of them left (see the Gospel of John 6:60). Today, the question still comes to us: “will you also go away?” (John 6:67). Is the holy Eucharist actually a sacrifice? Should we worship the Eucharist?

Introduction to the Sacraments: Lesson 12
A sacrament is a sacred sign instituted by Christ to give grace. Each word in this concise definition is chosen with precision and bears a great deal of meaning. This lesson explains exactly what is meant by “sign,” what is meant by “grace” how sacraments “give” grace, and how sacraments are not life magic. The requirements for a valid sacrament, the proper minister of the sacraments, and sacramentals will also be discussed in this lesson.

The Eucharist: Lesson 14
For many of us, Baptism and Confirmation were sacraments we received a long time ago. What did they do for us? Do you know how important they are? Sometimes Catholics are criticized for baptizing infants – find out why the Church encourages this practice. We’ll also discuss which is better, immersion or pouring, and what Noah has to do with this topic.

Penance: Lesson 15
Christ invites us to respond to evil, first of all, with a serious examination of conscience and the commitment to purify our lives. In effect, people and societies that live without ever questioning themselves have ruin as their only final destination. Conversion, on the other hand, while not preserving one from problems and misfortunes, allows one to face them in a different ‘way.’”

Matrimony: Lesson 16
The vocation to Matrimony is given by God the Father which “unites man and woman in an unbreakable bond of love and peace.” The Church also teaches that marriage is an “outpouring of love in the new covenant of grace is symbolized in the marriage covenant that seals the love of husband and wife….” Professor Peter Kreeft explores the Catholic Church’s theology of marriage, the state of marriage today and the virtues of the married state.

Holy Orders & Anointing of the Sick: Lesson 17
This podcast deals with two sacraments: Holy Orders and the Anointing of the Sick. All baptized people are called to contribute to the work of salvation. In the Church, priests of Jesus Christ are dedicated to the service of communion. So what is a priest? The letter of Saint James says that if someone is sick we are to call the priest so that they can pray over the sick person anointing him or her with oil in the name of the Lord. What do we believe about the sacrament of anointing?

Mary: Lesson 20
The Lord's Prayer: Lesson 19
Prayer: Lesson 18
The Lord’s Prayer is “the summary of the whole gospel,” Tertullian said. And we dare to pray it regularly. The Catechism teaches us that “The Lord’s Prayer brings us into communion with the Father and with his Son, Jesus Christ. At the same time it reveals us to ourselves. Praying to our Father should develop in us the will to become like him and foster in us a humble and trusting heart” (2799-2800). Essential to our Christian formation is the important fact: the Lord’s Prayer reveals us to ourselves. Indeed, Christ reveals us to ourselves.

What do you understand about the role of prayer in the Christian life? Pope Benedict XVI writes, “The Christian who prays seeks an encounter with the Father of Jesus Christ, asking God to be present with the consolation of the Spirit to him and his work.” The subject of prayer is discussed in this lesson, Prayer.

Mary’s place in salvation history was made clear in Pope Benedict XVI's homily at the Canonization of Frey Antônio de Sant'Anna Galvão in Brazil on May 11, 2007: “Mary, Mother of God and our Mother, stands particularly close to us at this moment.... She, the Tota Pulchra, the Virgin Most Pure, who conceived in her womb the Redeemer of mankind and was preserved from all stain of original sin, wishes to be the definitive seal of our encounter with God our Savior. There is no fruit of grace in the history of salvation that does not have as its necessary instrument the mediation of Our Lady.” In this lesson we learn of Mary’s place in Catholic theology and her place in our lives.
