Visitors ask...Latin abbreviation - A.M.D.G. et B.V.M.?
A.M.D.G. is an abbreviation for "ad maiorem Dei gloriam" (for the greater glory of God; the standard Jesuit motto of St. Ignatius Loyola). By adding "et" (and), the letters B.V.M. are meant to indicate "Beata Virgo Maria" (the Blessed Virgin Mary). So, the phrase is meant to indicate that some effort is dedicated "To the greater glory of God and the Blessed Virgin Mary."
Note the lack of a "j" in Latin. The letter "i" is found in "maiorem."
