“While all members of the family are called to live out the foundational Christian virtues, fathers and mothers have a responsibility for fostering these virtues within their children. They are responsible for nurturing the vocation of each child, showing by example how to live the married live, and taking special care if a child might be called to priesthood or consecrated life.”
– USCCB Pastoral letter Marriage: Love and Life in the Divine Plan
Vocations aren't discovered in a vacuum; it is within the context of a family that husbands and wives continue to discover their particular path to holiness, and where children first hear the call or feel the tug towards this or that vocation.
