 Supernumeraries devote a portion of their day to prayer, in addition to attending regular meetings and taking part in activities such as retreats.Due to their career and family obligations, supernumeraries are not as available to the organization as the other types of members, but they typically contribute financially to Opus Dei, and they lend other types of assistance as their circumstances permit.Unlike other types of members, supernumeraries are not required to be celibate.
