Canon LXX.

Women are not permitted to speak at the time of the Divine Liturgy; but, according to the word of Paul the Apostle, “let them be silent.  For it is not permitted to them to speak, but to be in subjection, as the law also saith.  But if they wish to learn anything let them ask their own husbands at home.”
