Altar society
An altar society or altar guild is a group of laypersons in a parish church who maintain the ceremonial objects used in worship. Traditionally, membership was limited to women and their most common functions are making floral arrangements for the sanctuary, caring for linens, and holding fundraisers to purchase items for the sanctuary, including vestments and altar vessels. Once the major volunteer organization for women in almost every parish, but with an increase in other lay ministries, and women working outside the home, there has been a decline in the number of parishes who still have altar societies . Today, especially in the United States, membership may include both men and women and functions in a similar manner as before, oftentimes with less emphasis on fundraising. The duties of members vary according to circumstances, in some instances including those which ordinarily fall within the sacristan's province, such as the vestments and altar vessels and making ready for the Mass. Some altar societies have expanded their scope of service to include charitable activities such as sending cards or telephoning homebound parishioners, or visiting nursing homes. They would either organise a fund for the maintenance and repair of church vessels  or work to maintain the vessels. Altar societies differ from tabernacle societies in that altar societies work for the benefit of the church to which they are attached and tabernacle societies work for the benefit of many different poor churches.
