Altar bread, also known as communion bread, host, or Eucharist, is a small, round wafer made of white flour and water. It is a staple in religious ceremonies in most Christian churches and is believed to represent the body of Christ. Priests bless and consecrate the altar bread before distributing it during mass. The term "altar bread" is usually used by the Catholic church, but other denominations refer to it by different names. Anglicans and Lutherans commonly use the term "communion bread," while Orthodox Christians refer to it as "prosphora." The term "host" is also widely used, and it derives from the Latin for "victim" or "sacrifice".
