chapter three deals with the vocation of the family according to the catholic tradition and the gospels. it stresses the sacramental nature of marriage, its indissolubility, and its role in the transmission of life. pope francis states that the family is an image of the trinity, christ's love for the church, and "the espousal of our human nature by the son of god." (paragraphs 71 and 73) this chapter touches on "imperfect situations" and "wounded families" and calls pastors "to exercise careful discernment of situations." ("familiaris consortio, 84")
