But the most curious contribution which Jones made to the Trinitarian controversy was a pamphlet entitled 'A Short Way to Truth, or the Christian Doctrine of a Trinity in Unity, Illustrated and Confirmed from an Analogy in the Natural Creation.' He shows that the powers of nature by which all natural life and motion are preserved are three--air, fire, and light. That these three thus subsisting together in unity are applied in Scripture to the Three Persons of the Divine Nature, and that the manifestations of God are always made under one or other of these signs. These three agents support the life of man. There is a Trinity in the body (1) the heart and blood-vessels; (2) the organs of respiration; (3) the nerves, the instruments of sensation; these three departments are the three moving principles of nature continually acting for the support of life. 'Therefore,' he concludes, 'as the life of man is a Trinity in Unity, and the powers which act upon it are a Trinity in Unity, the Socinians being, in their natural capacity, formed and animated as Christians, carry about with them daily a confutation of their own unbelief.'[453] In the year 1782, the Trinitarian controversy received a fresh impulse from the appearance in it of a writer whose eminence in other branches of knowledge lent an adventitious importance to what he wrote upon this subject. In that year, Dr. Priestley published his 'History of the Corruptions of Christianity,' which, as Horsley says, was 'nothing less than an attack upon the creeds and established discipline of every church in Christendom.' Foremost among these corruptions were both the Catholic doctrine of our Lord's divinity and the Arian notion of His pre-existence in a state far above the human. The great antagonist of Dr. Priestley was Dr. Horsley, who, first in a Charge to the Clergy of the Archdeaconry of St. Albans, and then in a series of letters addressed to Priestley himself, maintained with conspicuous ability the Catholic doctrine of the Trinity.
