OL BLSD SACRAMENT LAM HC Laminated single card. Meas 2-3/4"x 4-1/2" Back reads: To Our Lady of the Most Blessed Sacrament. Virgin Immaculate, Mother of Jesus and our Mother. We invoke you under the title of Our Lady of the Most Blessed Sacrament, because you are the Mother of the Savior who lives in the Eucharist. It was from you He took the flesh and blood which feeds us in the Sacred Host. We also invoice you under that title because the grace of the Eucharist comes to us through you, since you are the mediatrix, the channel through which God's grace reaches us!
