Know your Mass is a detailed, fully illustrated step-by-step explanation of the Traditional Latin Mass, the Holy Sacrifice as the re-enactment of Calvary. Reprinted in black and white, this text book from the 1950's is an excellent catechetical tool for all ages.
The manual presents the theology of the Mass in a manner easily understood by children preparing for their First Communion and yet instructive and informative for older students, young adults, teachers, parents and grandparents.
