소시니안주의(Socinianism (/səˈsɪniənɪzəm/)란 16세기와 17세기 폴란드 소 개혁교회안(the Minor Reformed Church of Poland )에서 폴란드 형제들에게 영항을 주었던 파우스토 소치니(Latin: Faustus Socinus)의 이름을 딴 기독교 교리체계이다.[1]같은 시기에 트란스베니아 유니테리안 교회에서도 활발하였다.[2]그들은 반삼위일체론자들이며 그리스도의 신성을 거절하였다.
하나님의 속성 중 전지성(모든 것을 아심)에 대해 사람의 미래에 대한 필요한 진리(확실히 발생할 일들)는 하나님이 아시지만, 조건적 진리(일어날지 안일어날지 모르는 일들)에 대해서는 하나님도 모르심.(하나님이 모든 것을 아시면, 인간의 자유의지는 존재할 수 없기 때문임)
