We have two traditions for celebrating our Mass, the Holy Eucharist in the Episcopal Church. We inherited these traditions from the Roman Catholic Church both in antiquity and more recently, in our own reform and renewal following the Second Vatican Council which impacted reform in our Church and many others. Below is a link to a beautiful and informative Catholic Answers video which explains the history. At St. Paul’s we celebrate Mass according to both traditions, which in itself is very Episcopal/Anglican!
