Applause during church services is traditionally regarded as taboo, in light of the sanctity of the proceedings; stress is on the aspect of worship rather than the personality of the individual preaching or singing during the service. This rule may be relaxed to permit applause in honor of the bride and groom when the newly married couple may turn to be greeted by the congregation following the exchange of vows. Applause may also be permitted at certain services in honor of a specific individual, such as the investiture of a new priest or minister. In less traditional congregations, particularly in contemporary, evangelical "megachurches", a more casual atmosphere exists and applause may be encountered as frequently as at any secular performance.
