From Pope St. John Paul II’s Apostolic Exhortation Familiaris Consortio (1981):
The contribution that can be made to the apostolate of the family by men and women religious and consecrated persons in general finds its primary, fundamental and original expression precisely in their consecration to God. By reason of this consecration, “for all Christ’s faithful religious recall that wonderful marriage made by God, which will be fully manifested in the future age, and in which the Church has Christ for her only spouse,”169 and they are witnesses to that universal charity which, through chastity embraced for the Kingdom of heaven, makes them ever more available to dedicate themselves generously to the service of God and to the works of the apostolate.
Hence the possibility for men and women religious, and members of Secular Institutes and other institutes of perfection, either individually or in groups, to develop their service to families, with particular solicitude for children, especially if they are abandoned, unwanted, orphaned, poor or handicapped. They can also visit families and look after the sick; they can foster relationships of respect and charity towards one-parent families or families that are in difficulties or are separated; they can offer their own work of teaching and counseling in the preparation of young people for marriage, and in helping couples towards truly responsible parenthood; they can open their own houses for simple and cordial hospitality, so that families can find there the sense of God’s presence and gain a taste for prayer and recollection, and see the practical examples of lives lived in charity and fraternal joy as members of the larger family of God.
I would like to add a most pressing exhortation to the heads of institutes of consecrated life to consider—always with substantial respect for the proper and original charism of each one—the apostolate of the family as one of the priority tasks, rendered even more urgent by the present state of the world.
