"X. Difficulties for Mary's Faith"
One might be tempted to think she had no need for believing without seeing - she had seen marvelous things. But yet there was for her a constant clash of what her senses reported, and what her faith said. Her senses would report: this seems like a very ordinary baby, with ordinary needs. Or she would be tempted to wonder at His staying home for 30 years when He was sent for so great a mission. Her faith would report: I must believe even so. One extraordinary Eucharistic minister once told me that ever since he was allowed to handle the Sacred Host, he found greater temptations against faith. That would be from the same sort of clash, except that for her it was much stronger and clearer.
