Peran Muallaf Center Nasional (MCN) Aya Sofya Indonesia dalam Menanggulangi Gerakan Kristenisasi di Indonesia

This research aims to examine the role of the Muallaf Center Nasional (MCN) Aya Sofya Indonesia in countering the increasingly massive Christianization movement in Indonesia. Using a qualitative approach through descriptive-analytical methods and a sociological approach, this research found that MCN Aya Sofya implements counter-strategies through three main approaches. First, collaborating with preachers and experts in religious studies, particularly in the fields of Christology and Judaism, to provide guidance to converts and equip them with a strong religious understanding. Second, MCN utilizes digital media such as websites, Instagram, YouTube, and Facebook as means for preaching, disseminating Islamic information, and interfaith dialogue. Third, MCN implements the 3D pattern (Dakwah, Dialog, and Diskusi) as the main strategy in educating the community and building effective religious communication. This pattern is considered flexible and responsive to various situations in facing the Christianization movement. This research concludes that MCN Aya Sofya plays a very significant role in strengthening Islamic identity and protecting the faith of converts amidst the dynamics of the Christianization movement in Indonesia.
