ecclesialis

Ecclesialis is a Latin adjective meaning "of the church" or "ecclesial." It derives from Ecclesia, Latin for "church," combined with the adjectival suffix -alis. In Latin, ecclesialis is used to describe things pertaining to the church, its doctrine, life, or institutions, and appears in both classical and medieval ecclesiastical writings to designate church-related concepts.

In English usage, the form ecclesial is borrowed from Latin and is employed in theological and academic contexts to denote matters related to the church as a community or institution. It appears in discussions of ecclesial communities, ecclesial authority, and other church-centered topics, often with a focus on the church as a living body rather than solely on its formal structures.

A closely related term is ecclesiastical, which is more common in English and can describe church matters in a formal or institutional sense. While the two terms overlap, ecclesial tends to emphasize the church as a community or body, whereas ecclesiastical can carry a stronger sense of organizational, legal, or procedural aspects.
