Disagreement concerning religious doctrine

Incompatible forms of worship
Liturgical conflicts
In the case of Christian churches, for example, there are differences of opinion as to: the relation of word and sacrament; the blessing of the eucharistic elements; scope of liturgical and non-liturgical forms of worship; worship led by any member of the congregation rather than by an ordained minister; the sacrificial aspect of the eucharist; the distinction between saints and blessed saints.
