He writes:"Christians are distinguished from other men neither by country, nor language", living in such places "as the lot of each of them has determined, and following the customs of the natives in respect to clothing, food, and the rest of their ordinary conduct, they display to us their wonderful and confessedly striking method of life. They dwell in their own countries, but simply as sojourners. As citizens, they share in all things with others, and yet endure all things as if foreigners. Every foreign land is to them as their native country, and every land of their birth as the land of strangers... They pass their days on earth, but they are citizens of heaven. They obey the prescribed laws, and the same time surpass the laws by their lives... they are reviled and bless"?
Then, speaking of God, he says:He "who is Almighty, the Creator of all things, ...has sent from heaven, and placed among men, Him who is the truth, and the holy and incomprehensible Word, and has firmly established Him in their hearts. He did not, as one might have imagined, send to men any ...angel or ruler ...but the very Creator and Fashioner of all things - by whom He made the heavens - by whom He enclosed the sea within its proper bounds" - whom the stars obey. "This messenger He sent to them... As a king sends his son who is also a king, so sent He Him; as God He sent Him; as to men He sent Him; as a Saviour He sent Him." Not as judging us He sent Him though "He will yet send Him to judge us, and who shall endure His appearing?" As to the delay in sending the Saviour, God has always been the same, but waited in His long-suffering. He had "formed in His mind a great and unspeakable conception, which He communicated to His Son alone." As long as He concealed His own wise counsel He appeared to neglect us, but this was to make it manifest that of ourselves we cannot enter into the kingdom of God. But when the appointed time had come, "He Himself took on Him the burden of our iniquities, He gave His own Son as a ransom for us, the Holy One for transgressors, the blameless One for the corruptible, the immortal One for them that are mortal. For what other thing was capable of covering our sins than His righteousness? By what other one was it possible that we, the wicked and ungodly, could be justified, than by the only Son of God. O sweet exchange! O unsearchable operation! O benefits surpassing all expectation! That the wickedness of many should be hid in a single righteous One, and that the righteousness of One should justify many transgressors!"
