The Altar Crucifix is placed upon the altar is a reminder to the congregation and the priest of the believed nature of the Eucharist as the actual body of Christ; the altar itself symbolically represents the way to Gologatha. It is for this reason that Roman Law decrees it necessary to have the crucifix upon the altar whenever Mass is celebrated. Specifically, it is placed directly in between the Candlesticks in such a way that it is conveniently seen by the people.
This style of the altar crucifix has been used in the Bohemian churches and Cathedrals for over 100 years.
