I ask the church body to pray for me when I need it, and I have seen miracles happen from the praying. I don't ask just anybody to pray for me. Since the church body is the body of Christ, is in Christ, there is no mediator but Christ
You have just given the Catholic argument, except that you won't include Mary and the saints in heaven as part of the Church.
Um, a nice answer, but a bit disingenuous. Certainly, the Church is the Body of Christ. Yet I hardly believe when you ask the 'church body' to pray for you, every single member of the Body of Christ is praying specifically for you -unless yours is a somewhat exclusive definition of the Body of Christ limited to your immediate locale. Hence, you are asking certain 'parts' of the Body of Christ to pray for you. Following this logic, when Catholics ask Mary or the other saints to pray for us, we, too, are asking the Body of Christ to pray for us.
It would seem to me, then, this whole 'Catholics set up a mediator between themselves and Christ' business is bogus. The real issue is whether the saints in heaven can hear our prayers. In fact, the argument you give is something of a restatement of the theology of the communion of saints. The difference between us, then, is not some issue about mediation but, rather, what constitutes the communion of saints.
