Catholics received precise instructions as to the Marian Year. Among other things, they had to celebrate solemnly all the Marian festivities and make a pilgrimage to the churches dedicated to the “Madonna.” They could also benefit from the “plenary indulgence”b by devoutly participating in Marian holidays and liturgical festivities or by piously receiving the papal blessing imparted by the bishop, even by means of a radio or television broadcast. They were counseled that greater value should be attributed to the altar dedicated to Mary in each Catholic church.
