2 The adaptation and renewal of the religious life includes both the constant return to the sources of all Christian life and to the original spirit of the institutes and their adaptation to the changed conditions of our time. This renewal, under the inspiration of the Holy Spirit and the guidance of the Church, must be advanced according to the following principles: a) Since the ultimate norm of the religious life is the following of Christ set forth in the Gospels, let this be held by all institutes as the highest rule. b) It redounds to the good of the Church that institutes have their own particular characteristics and work. Therefore let their founders' spirit and special aims they set before them as well as their sound traditions-all of which make up the patrimony of each institute-be faithfully held in honor. c) All institutes should share in the life of the Church, adapting as their own and implementing in accordance with their own characteristics the Church's undertakings and aims in matters biblical, liturgical, dogmatic, pastoral, ecumenical, missionary and social. d) Institutes should promote among their members an adequate knowledge of the social conditions of the times they live in and of the needs of the Church. In such a way, judging current events wisely in the light of faith and burning with apostolic zeal, they may be able to assist men more effectively. e ) The purpose of the religious life is to help the members follow Christ and be united to God through the profession of the evangelical counsels. It should be constantly kept in mind, therefore, that even the best adjustments made in accordance with the needs of our age will be ineffectual unless they are animated by a renewal of spirit. This must take precedence over even the active ministry.
