The Church of England sent out many a missionary to the Muslim world over the years, but less known (and less active) is the Episcopal Church in the USA. Horatio Southgate was one such missionary, he did two tours in what was then the Ottoman Empire. At one point, he got in trouble with some of his fellow missionaries, who wrote back to the USA about him, and he had to write a letter in his defense. You can read it here.
Note here one of the issues of complaint, and his defense of himself:
Never so much as once did I receive the Sacrament of Holy Communion from the [non-Episcopal] missionaries at Constantinople; never so much as once take any part with them in the administration of it. They may, perhaps, refer to a single instance in which I did receive it, from other Congregational missionaries, in another place. If so, why do they speak of sitting down "with us," "receiving from our hands," and "taking part with us? Those who write are the missionaries at Constantinople, and they say expressly, in two different places in their pamphlet, (pp. 5 and 30,) that they speak throughout only of what concerns themselves and their station. But again, they speak of this intercommunion as if it had been a habit with me; whereas I never but once partook of the Communion in connection with Congregational missionaries in Turkey[...]
