I have been going to knock shrine for years now. But I never figured out why did Our Lady, St. Joseph and St. John the Evangelist appeared at the South gable of the church. And especially why did St. Joseph and St. John the Evangelist come when no other appearance witness these two people with the blessed mother of god?? If you think that strange what do you think of this “On the altar stood a lamb, facing the west and behind the lamb a large cross stood upright? Angels hovered around the lamb for the duration of the apparition” the lamb was the sign of the lamb of god. And what is the lamb of god meant to mean???. Also was St. John the Evangelist a bishop on earth??. Is their mass in heaven??
