ABSTRACT The integrity of the marriage of the people of God, the Church of Tuan Pantai Makasar Oekusi-RDTL is the highest hope and dream of Catholic families in the Oecusse enclave region-Democratic Republic of Timor Leste. The dream of these Catholic families is also identified as the hope and dream of the Catholic Church of Timor Leste and the Democratic Republic of Timor Leste. In the linearity of thought, the integrity of marriage requires the appreciation of moral values. The appreciation of moral values that have a positive impact on the integrity of marriage must be based on a deep understanding of moral values. In this framework of thought, the activity of socializing moral values for the people of God, the Church of Tuan Pantai Makasar Oekusi-RDTL is the choice of Community Service Activities (PKM) in the Field of Philosophy. The service method is divided into two stages, namely the preparation stage in the form of a survey of the service location and scientific study of the service topic, the implementation stage in the form of socialization of moral values that have a positive impact on the integrity of the marriage of Catholic families, and in-depth socialization material in the form of Focus Group Discussion (FGD). The purpose of this activity is to increase the understanding of the people of God at the Tuan Pantai Makasar Oekusi Church about moral values that are important for maintaining the integrity of Catholic families' marriages. Through this activity, the people of God are increasingly aware of the importance of moral values in maintaining the integrity of marriage and are committed to living out moral values in organizing their families towards harmonious and happy families.
