The eternal Son of God, in becoming man, took a human nature from the Virgin Mary. Thus was born a being who was both God and man. As God, this Second Person of the Holy Trinity always existed, and from Him in eternity the Holy Ghost always proceeds, as from the Father also. In this sense the Holy Ghost does not give being to the Son. But the human nature, which began in time, was due to the operation of the Holy Ghost, and was assumed by the Son. There is no inconsistency in this doctrine.
