Q & A with Fr Job:
Question: How did the teaching concerning the Mysteries arise? Why is tonsure a Mystery, but burial not? Why do certain priests say: “Everything in the Church, it’s all a Mystery"?
Answer: According to the teaching of the Orthodox Church, a Mystery is a sacred act in which, under a visible form, the invisible grace of the Holy Spirit is given. They were established by the Savior and the Holy Apostles. The ritual aspect was formed gradually.
Monastic tonsure is not a Mystery, Burial is the prayerful commemoration and rite of forgiveness with the departed children of the Church. A Mystery may be performed only on the living. He upon whom a Mystery is performed must prayerfully participate in it.
