Did you ever notice this symbol located in the center of the altar?
It is a “Christogram” or a religious symbol for Jesus Christ. Originating in Medieval Western Europe, JHS (or IHS) is a Latin acronym for Jesus Honinum Salvator – Jesus Savior of Mankind.
It is impressive that this Christogram has survived all these centuries and can be seen throughout the world in many Catholic, Episcopalian and Protestant churches. Often this symbol is inscribed on the Holy Eucharist.
