Cultural adaptation of the liturgy involves integrating local customs, symbols, and expressions into public worship (like Mass) to make it more relatable and meaningful for a specific culture, a principle emphasized by Vatican II, moving beyond rigid uniformity to allow diverse, culturally-rooted expressions while preserving core Christian truths, as extensively explored by liturgical scholar Anscar J. Chupungco in his key work, 'Cultural Adaptation of the Liturgy'. This process, also known as inculturation, aims to root the Gospel in local cultures, finding common ground in fundamental human values like giving thanks, sharing meals, and expressing community.
