A protestant family member asked me where in scripture it says that "communion" is to be received weekly on the Sabbath. His church will distribute communion every six weeks or so and it is "consecrated" but is only seen as a symbol of Christ as bread and wine. i.e. no transubstantiation.
I explained that Sacred Scripture is not the only authority on matters of faith in Catholicism but that Sacred Tradition is as well. I mentioned that there is an "early church fathers" document called the Didache and that it was evidence of the earliest traditions by the early church for Weekly Eucharist. Am I on on track here? Are there other references to the Early Church Fathers I could share with him?
I am not trying to convince him to be Catholic...that is for the Holy Spirit...but I did appreciate his inquiry into our practice of receiving the Eucharist on Sundays (and even daily). I'd like to be able to continue the conversation with him. Thanks for any help you can offer.
