15. Given the importance of the theme, and aware of the different initiatives which have been made in this direction by not a few Episcopal Conferences and many diocesan Bishops, the Pontifical Council for the Family extends the invitation to continue in this pastoral service with renewed commitment. The Episcopal Conferences have prepared useful material that can contribute to marriage preparation and following up family life. In continuity with the directives of the Apostolic See, the Pontifical Council offers these starting points for reflection with exclusive reference to one part of the above-mentioned Directory: that related to preparation for the sacrament of Marriage. Hence this part of the directory can be more useful in delineating and developing those aspects which are necessary for the proper preparation for marriage and Christian family life.
