# Pater noster, qui es in caelis,
# sanctificētur nomen tuum.
# Adveniat regnum tuum.
# Fiat voluntas tua,
# sicut in caelo, et in terrā.
# Panem nostrum quotidiānum da nobis hodie,
# et dimitte nobis debĭta nostra,
# sicut et nos dimittĭmus debitorĭbus nostris.
# Et ne nos indūcas in tentatiōnem,
# sed libĕra nos a malo.
# Amen.
