Unitarianismus
Unitarianismus sive Unitarismus (ab unitate) est  Christianismi motus theologicus, qui ex suo intellectu Dei ut persona una, recte contra Trinitarianismum appellatus, quem Christiani habent eorum deum in tribus personis consubstantialibus ut singulum ens constantibus. Unitariani dicunt Iesum certo sensu esse filium Dei, sed singulum deum non esse. Unitarianismus etiam reiectione nonnullarum aliarum doctrinarum Christianarum usitatarum innotuit, inter quas fuerunt doctrinae soteriologiae, peccati originalis, et praedestinationis, atque, in historia recentiore, inerrantia biblica. Inter liberalem ecclesiarum familiam digeri potest.

Motus Unitarianus, quamquam Unitarianus primum non appellatus, paene simul coepit in Polonia-Lithuania et Transylvania medio saeculo sexto decimo, inter cuius assectatores fuerunt aliqui Italici. In Anglia, prima ecclesia unitariana anno 1774 in Via Essex Londinii constituta est, ubi praesidium Britannicum hodiernum iam patet. Prima sollemnis fidei Unitarianae acceptio per omnem congregationem in America in Cappella Regis Bostoniae facta est, unde Iacobus Freeman doctrinam unitarianam anno 1784 docere coepit, et, rector rite creatus, Librum Precum secundum doctrinas Unitarianas anno 1786 retractavit.
