Missing worship is treated differently across traditions: Catholicism considers missing Sunday Mass a mortal sin, most Protestant churches encourage attendance without calling it sinful, Orthodox Christians are expected to attend Divine Liturgy, Islam considers missing Friday prayer sinful for men, and Judaism values communal prayer but doesn't treat absence as a formal sin.
