The science of research and interpretation of the type of worship is called liturgy, which is the branch of the science of Theology, which studies Christian Worship, public, but also private prayer.  In this series of liturgical lessons we will examine the genesis and evolution of the treasure of our liturgical tradition through the sources, as well as the connection between Christian and Jewish worship.  In addition, we will emphasize the mysteries of baptism and anointing, from their divine establishment until the end of the 4th Century.
