Utraquism

Utraquism (from the Latin sub utraque specie, meaning “in both kinds”) was a Christian dogma first proposed by Jacob of Mies in 1414. It maintained that the Eucharist should be administered “in both kinds” — as both bread and wine — to all the congregation, including the laity. (The practice at the time was for only the priests to partake of the wine).
