Although Michael Servetus was critical of the Trinity there is a fine line between his beliefs and those of Trinitarian beliefs.

Extract: Theology[edit]
Because of his rejection of the Trinity and eventual execution by burning for heresy, Unitarians often regard Servetus as the first (modern) Unitarian martyr —though he was a Unitarian in neither the 17th-century sense of the term nor the contemporary sense. Sharply critical though he was of the orthodox formulation of the trinity, Servetus is better described as a highly unorthodox trinitarian.[50]
Aspects of his thinking—his critique of existing trinitarian theology, his devaluation of the doctrine of original sin, and his fresh examination of biblical proof-texts—did influence those who later inspired or founded unitarian churches in Poland and Transylvania.[50]
Other non-trinitarian groups, such as Jehovah's Witnesses,[51] and Oneness Pentecostalism,[52] also claim Servetus had similar non-trinitarian views as theirs, although he had other views that they never believed in.[1] Oneness Pentecostalism particularly identifies with Servetus' teaching on the divinity of Jesus Christ and his insistence on the oneness of God, rather than a Trinity of three distinct persons: "And because His Spirit was wholly God He is called God, just as from His flesh He is called man."[53] Swedenborg wrote a systematic theology that had many similarities to the theology of Servetus.
