Consubstantial
CONSUBSTANTIAL
A term of like import with co-essential, denoting something of the same substance with another. Thus we say that Christ is consubstantial with the Father. The term consubstantial was first adopted by the fathers of the councils of Antioch and Nice, to express the orthodox doctrine the more precisely, and to serve as a barrier and precaution against the errors and subleties of the Arians, who owned every thing except the consubstantiality. The Arians allowed that the word was God, as having been made God; but they denied that he was the same God, and of the same substance with the Father: accordingly they exerted themselves to the utmost to abolish the use of the word. The emperor Constantine used all his authority with the bishops to have it expunged out of the symbols; but it was retained and is at this day, as it was then, the distinguishing criterion between an Athanasian and an Arian.

consubstantial
(Latin: con, with; substantia, substance)
A translation of the Greek, homousios, chosen at the Council of Nica (A.D. 325 ) as the only correct word to express the nature of the Son of God. He is not inferior to the Father, nor posterior, nor merely like unto Him, but identical in substance and in essence with Him. He is truly God, God of very God, consubstantial with the Father, as the Nicene Creed has it, having, or rather, being, the Godhead no less than the Father.

Consubstantial
a word of similar import with co-essential, denoting something of the same substance with another. The term was first used by the fathers of the councils of Antioch and Nicaea to express the orthodox doctrine more precisely. At first the term had only a negative use, as against the Arian heresy; but after the adoption of the Nicene Creed it became a test- word of orthodoxy.
