Arcissevius John, (Polon. Arciszewski,) Junior, was employed as a Missionary for the diffusion of Unitarianism in foreign countries, by the Assembly of Daszow, in 1648, at an annual salary of a thousand florins; and had, as a colleague and fellow-labourer, Christopher Crellius, surnamed Spinovius. In 1649, at the Assembly of Raszcow, it was left to his own option to fix the scene of his labours wherever he pleased, provided his choice should be favourable to the interests of the Church.
