UBIQUITARIANS, in church-history, a sect of heretics who sprung up in Germany about the year 1590, and maintained that the body of Christ is ubique, "everywhere," or in every place, at the same time. However, they were not quite agreed among themselves; some holding that the body of Jesus Christ, even during his mortal life, was every where; and others dating the ubiquity of his body from the time of his ascension only.
