The Covid-19 situation makes it difficult for the Church to move freely. This encourages the Church to struggle with social media to demonstrate the existence of its ministry amid the Covid-19 situation. Social media advances that the Church has responded well to have made the proclamation of faith not limited by space and time. In proclaiming the faith in this day and age, the Church needs the active participation of young Catholics (OMK). The focus of this research is to study the involvement of OMK St. Agustinus Ketapang in proclaiming the faith in social media. Participation in OMK St. Augustine Ketapang is a very helpful thing for the growth of the Catholic faith. The method used in this research is literature study and quantitative data collection through questionnaires. OMK St. Agustinus Ketapang already has a good understanding of social media and its use in improving the quality of faith. Small steps have been taken by OMK St. Agustinus Ketapang in using social media as a medium for proclaiming faith as a good initial stage to realize his mission as a member of the Church in the Covid-19 situation.
