MARY, bright moon of purity, I rejoice with thee, because the mystery of thy immaculate conception was the beginning of salvation for the race of man and the joy of the whole world. I thank and bless the ever-blessed Trinity, who thus did magnify and glorify thee; and I beg of thee to obtain for me the grace so to profit by thy dear Son's death and passion, that His precious blood may not have been shed in vain for me upon the cross, but that, after a holy life, I may reach heaven in safety.
