Pope Gelasius in his ninth letter (chap. 26) to the bishops of Lucania condemned the evil practice which had been introduced of women serving the priest at the celebration of Mass. Since this abuse had spread to the Greeks, Innocent IV strictly forbade it in his letter to the bishop of Tusculum: 'Women should not dare to serve at the altar; they should be altogether refused this ministry.' We too have forbidden this practice in the same words.
