 In 1565, the Diet (Sejm) of Piotrków excluded anti-Trinitarians from the existing synod of the Polish Reformed Church (henceforth the "Ecclesia maior") and Unitarians began to hold their own synods as the "Ecclesia minor".Known by various other names (of which Polish brethren and Arian were the most common), at no time in its history did this body adopt for itself any designation save "Christian".Originally Arian (but excluding any worship of Christ), and Anabaptist, the "Minor Church" was (by 1588) brought round to the views of Fausto Sozzini, who had settled in Poland in 1579, and who denied the pre-existence of Christ, while accepting the virgin birth (see Socinianism).
