Every Pflaum Gospel Weeklies lesson is based on the Sunday Gospel and related Church doctrine. Each child receives a copy of the What the Church Believes and Teaches Catechism handbook at the beginning of the school year. In each lesson, the editors reference a section of this handbook, which reinforces the doctrine. The Teaching Guides include a plan for teaching the doctrine, but those looking for more guidance and background will find the support they need in these Teaching Companions. They are available for each level to view online or download and print for regular reference. Teaching Companions are available in English and Spanish.
