Question: can a catholic receive communion in an episcopal church

Answer: No, The Catholic Church distinguishes between Churches whose celebration of the Eucharist, as well as holy orders, it recognizes as valid and those of other Christian communities. In the case that it is impossible to approach a Catholic minister, that it is a case of real need or spiritual benefit,and that the danger of error or indifferentism is avoided, the Catholic Church permits its faithful to receive Communion in Orthodox Churches, although Orthodox Churches do not honour this and only permit Orthodox Christians to receive Communion in Orthodox Churches. The Catholic Church does not ordinarily allow a Catholic to receive communion in a Protestant church, since it does not consider Protestant ministers to be priests ordained by bishops in a line of valid succession from the apostles, although Lutherans, Moravians, and Anglicans teach that they ordain their clergy in lines of apostolic succession. It applies this rule also to the Anglican Communion, pursuant to Apostolicae curae, a position that the Church of England disputed in Saepius officio.
