Martin always called the blacks and Indians "hijos" ("my children"), and because of this filial love, he often found himself in situations in which he had to protect and defend the poor, as fathers and mothers do with their children. One day someone stole the mattress and blanket of a black man who was one of Martin's helpers in the infirmary. Upon hearing of it, Martin immediately said, "You stay here," and then he went directly to the cell of one of the friars, where he found the stolen articles.  Scolding the friar for not keeping a better eye on the priory servant who had stolen the things, Martin said: "Father, if your servant does not have a bed, then buy him one. He shouldn't be going and stealing one from someone else." Martin picked the mattress up and carried it back to his helper.
