The Order of Christian Initiation of Adults (OCIA) is the Church’s ritual for welcoming and forming adults and children of catechetical age in the way of Jesus as it is lived in the Roman Catholic tradition. In this resource, Fr. Ronald J. Lewinksi provides a basic and thorough introduction to the Church’s vision for the process of Christian initiation, guiding initiation ministers through the various rituals and steps of the OCIA through the lens of conversion, evangelization, and discipleship. This book is an excellent resource for new and experienced initiation ministers as well as for those who seek a deeper understanding of how the Church welcomes and initiates adult Catholic Christians. This revised edition has been updated to reflect the new translation of the Order of Christian Initiation of Adults
