Christadelphians exhibit varied approaches to Mark 16:9-20 depending on textual awareness and theological emphasis. Some Christadelphian communities, particularly those with higher biblical literacy, acknowledge the textual problems and limited authority of the longer ending. Others, particularly more conservative or isolated communities, may cite the passage without extensive discussion of textual issues. The signs and wonders promised in Mark 16:17-18 are generally not treated as normative for current Christadelphian practice, as the Christadelphian tradition does not emphasize charismatic gifts.

The tension between textual criticism and practical use of Scripture reflects broader Christadelphian engagement with modern scholarship while maintaining biblical authority.
