Marathonios. Against the Macedonians or Spirit-Contesters. If our God and Saviour after becoming Incarnate transmitted the Most Holy Spirit, counted as completing the Holy Trinity and by His invocation in Holy Baptism as freeing from sins, but on the Sacramental Table revealing ordinary bread to be His own Body in Taking Flesh, how is it then that you teach, you crackbrained fellow, that (the Spirit) is made or created or belongs to subject nature and is not parent to and of the same substance as the royal nature? For if subject, let it not be counted with the Master. And if it is a creature, let it not be compounded with the Creator. But it is united and counted together, since an exact exponent of such belief must believe Christ, when He teaches infallibly concerning His own substance, even if you do not accept it, as one who would be wiser and boasts of knowing heavenly (realities) better than God or who rather prates insolently against God.
