If you are Lutheran, how often should you have Communion in your services? Here is what the Augsburg Confession says:
Because the Mass is for the purpose of giving the Sacrament, we have Communion every holy day, and if anyone desires the Sacrament, we also offer it on other days, when it is given to all who ask for it. – Article XXIV: 34
To be Lutheran should mean to have Communion at least every Sunday, as well as on other days.
