 For early unitarians such as Henry Hedworth, who introduced the term "Unitarian" from Holland into England in 1673, the idea that Unitarianism was "Biblical" was axiomatic, since the whole thrust of the 16th and 17th century Unitarian and Arian movements was based on "sola scriptura" argumentation from Scripture, as in the case of the Christological writings of Isaac Newton.Theophilus Lindsey established the first avowedly Unitarian church in England in 1774 at Essex Street Chapel.Nontrinitarianism was against the law until the Doctrine of the Trinity Act 1813, but legal difficulties with the authorities were overcome with the help of barrister John Lee, who later became Attorney General.
