Weekly services are held in meetinghouses. These take an hour and involve the blessing and taking of the sacrament of bread and wine in remembrance of the body and blood of Christ. Once a month the service involved personal testimony from the congregation. The sacraments in LDS church are called saving ordnances. Mormons believe they must not only have faith and repent but also be baptised (by immersion and by a Mormon priesthood holder) and bring forth good works. Mormons consider their weekly Eucharist as a means of renewing their baptismal covenant and being repeatedly cleansed from sin. Although the grace of Jesus plays a role in salvation, each Mormon must "work out his own salvation." .
