Angel An angel, especially according to Abrahamic religions, is a spiritual being superior to humans in power and intelligence. Angels are typically described as benevolent, dreadful, and endowed with wisdom and knowledge of earthly events, but not infallible; for they strive with each other, and God has to make peace between them. Most of them serve either as intermediaries between Heaven and Earth, or as guardian spirits.
Altar An altar is any structure upon which offerings such as sacrifices are made for religious purposes, and by extension the 'Holy table' of post-reformation Anglican churches. Altars are usually found at shrines, and they can be located in temples, churches and other places of worship. Today they are used particularly in Christianity, Buddhism, Hinduism, Shinto, Taoism, as well as in Freemasonry. Also seen in Neopaganism and Ceremonial Magic. Judaism used such a structure until the destruction of the Second Temple. Many historical faiths also made use of them, including Greek and Norse religion.
