Post-truth is a floating culture regarding democracy, culture, conflicts of interest, etc. The post-truth era alters people's focus, particularly when it comes to matters of faith, such as catechism. This is why catechists need to know what's happening around them to help people get through the "post-truth" era. This research is meant to help catechists, who are responsible for communicating and leading the Catechism of the People, face the challenges of the "post-truth" era. The methodology employed is a qualitative approach based on library research. This study describes the competencies required of catechism facilitators in the post-truth age, namely theological competence (cyber-theology) with the Holy Spirit as the inspiration, spiritual competence (Christ as the spiritual center), digital technology competence (data-based evangelization), intercultural communication competence (language and culture, metanoia of ethnocentrism), and ICT (Information, Communication, and Technology) skills. The digital age in Indonesia allows the church to fulfill its mission by promoting adaptive and transformative approaches. The church (in this case, the catechists) must be proactive and offer new ways of doing things while keeping their Catholic identity. Digital dialogue, blogging about faith, digital discourse, and making a digital movement are all examples of digital catechesis, which is about building digital collaboration.
