A religious rite practiced by the ancients, and performed before any act of devotion. It consisted in washing the hands, and sometimes the whole body, in lustral or consecrated water. It was intended as a symbol of the internal purification of the heart. It was a ceremony preparatory to initiation in all the Ancient Mysteries.
The ceremony is practiced with the same symbolic import in some of the high degrees of Masonry. So strong was the idea of connection between lustration and initiation, that in the low Latin of the Middle Ages lustrare meant to initiate. Thus Du Cange (Glosarium) cites the expression "lustrare religione Christianorum" as signifying "to initiate into the Christian religion." — ( Exodus 29:4 - Leviticus 14:8 - Deuteronomy 21:6 )
