(Intro and Who is the Holy Spirit?)
Sent by the Spirit - Episode 1: Who is the Holy Spirit?
Who is the Holy Spirit? Before we can fully understand the Sacrament of Confirmation, we need to first understand who the Holy Spirit is. The Holy Spirit is not a divine force, or merely the spirit of God, the Holy Spirit is the third divine Person of the Holy Spirit who comes to dwell in our souls through the Sacrament of Baptism. In this session, Dr. Pitre will help you to come to know the Holy Spirit in a deeper way, especially how the Holy Spirit is present throughout all of salvation history as God prepares us to be sealed with the gift of the Holy Spirit.
(Confirmation and Pentecost)
Sent By The Spirit - Episode 2: The Grace of Pentecost
Fifty days after Easter, the Holy Spirit descended upon the Apostles with great power and transformed the Apostles to become great evangelists announcing to all present the Good News of the love and mercy of Jesus Christ. In this session, Dr. Pitre will discuss how the Sacrament of Confirmation is our own personal Pentecost through which the Holy Spirit transforms and empowers us for the mission of evangelization.
Sent By The Spirit - Episode 3: The Rite of Confirmation
Through the sacraments, God desires that we know visibly and tangibly what he is doing unseen within our souls. God communicates this in the sacrament through visible signs, words, and actions. In this session, Dr. Pitre will walk through the Rite of Confirmation and explain how the visible signs and words of Confirmation impart and communicate the grace and power of the Holy Spirit.
