Generally speaking, no. Most Anglican Churches operate an 'open table' meaning that anyone who normally receives communion in another church (whether it be Catholic, Methodist or whatever) are welcom to receive communion in the Anglican Church.hey therefore do not regard communion at a Methodist Church as a valid sacrament although theystill regard it as a memorial of Him. Communion from an Orthodox Church is considered valid by the Catholic Church so Catholics can receive it from them but only in cases where it is impossible to attend a Catholic mass.
For the national churches that make up the world-wide Anglican Communion, sharing holy communion with members of other denominations is a way of growing together in unity. For the Catholic Church, sharing in eucharistic communion = ecclesial communion.n situations of pastoral need, Catholics have the approval of their own Church to receive the eucharist only in the Polish National Catholic Church, the Syrian Church, and in Orthodox Church, though the latter has not given a corresponding approval so the door is really not open there.
