Augustine of Hippo
Catena Aurea · Johannesevangelium 3
—and no man receiveth his testimony. He that hath received his testimony hath set to his seal that God is true. For he whom God hath sent speaketh the words of God: for God giveth not the Spirit by measure unto him. The Father loveth the Son, and hath given all things into his hand. He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him.
(Tr. xiv. c. 8) Or thus; There is a people reserved for the wrath of God, and to be condemned with the devil; of whom none receiveth the testimony of Christ. And others there are ordained to eternal life. Mark how mankind are divided spiritually, though as human beings they are mixed up together: and John separated them by the thoughts of their heart, though as yet they were not divided in respect of place, and looked on them as two classes, the unbelievers, and the believers. Looking to the unbelievers, he saith, No man receiveth his testimony. Then turning to those on the right hand he saith, He that hath received his testimony, hath set to his seal.
