Holy Fathers on the Name of God: St. John Chrysostom

"And whatsoever ye do," he saith, "in word or in deed, do all in the Name of the Lord Jesus, giving thanks to God the Father through Him."

For if we thus do, there will be nothing polluted, nothing unclean, wherever Christ is called on. If thou eat, if thou drink, if thou marry, if thou travel, do all in the Name of God, that is, calling Him to aid thee: in everything first praying to Him, so take hold of thy business. Wouldest thou speak somewhat? Set this in front. For this cause we also place in front of our epistles the Name of the Lord. Wheresoever the Name of God is, all is auspicious... Do all in the Name of the Lord, and all shall be prospered to thee. Whereonsoever the Name is placed, there all things are auspicious. If it casts out devils, if it drives away diseases, much more does it render business easy.

And what is to "do in word or in deed"? Either requesting or performing anything whatever. Hear how in the Name of God Abraham sent his servant; David in the Name of God slew Goliath. Marvelous is His Name and great. Again, Jacob sending his sons saith, "My God give you favor in the sight of the man." (Gen. xliii. 14.) For he that doeth this hath for his ally, God, without whom he durst do nothing. As honored then by being called upon, He will in turn honor by making their business easy. Invoke the Son, give thanks to the Father. For when the Son is invoked, the Father is invoked, and when He is thanked, the Son has been thanked.

These things let us learn, not as far as words only, but to fulfill them also by works. Nothing is equal to this Name, marvelous is it everywhere. "Thy Name," he saith, "is ointment poured forth." (Cant. i. 3.) He that hath uttered it is straightway filled with fragrance. "No man," it is said, "can call Jesus Lord, but by the Holy Ghost." (1 Cor. xii. 3.) So great things doth this Name Work. If thou have said, In the Name of Father, and Son, and Holy Ghost, with faith, thou hast accomplished everything. See, how great things thou hast done! Thou hast created a man, and wrought all the rest (that cometh) of Baptism! So, when used in commanding diseases, terrible is The Name... If thou chant this incantation with faith, thou wilt drive away both diseases and demons, and even if thou have failed to drive away the disease, this is not from lack of power, but because it is expedient it should be so. "According to Thy greatness," he saith, "so also is Thy praise." (Ps. xlviii. 10.) By this Name hath the world been converted, the tyranny dissolved, the devil trampled on, the heavens opened. We have been regenerated by this Name. This if we have, we beam forth; This maketh both martyrs and confessors; This let us hold fast as a great gift, that we may live in glory, and be well-pleasing to God, and be counted worthy of the good things promised to them that love Him.
