In chapter xxiii., he again asserts that "in the times of Enoch" no one "observed Sabbaths." He then protests against Sabbatic observance as follows:-- "Do you see that the elements are not idle, and keep no Sabbaths? Remain as you were born. For if there was no need of circumcision before Abraham, or of the observance of Sabbaths, of feasts and sacrifices, before Moses; no more need is there of them now, after that, according to the will of God, Jesus Christ the Son of God has been born without sin, of a virgin sprung from the stock of Abraham." That is to say, there was no Sabbatic institution before Moses, and neither is there any since Christ. But in chapter xxiv., Justin undertakes to bring in an argument for Sunday, not as a Sabbath, but as having greater mystery in it, and as being more honorable than the seventh day. Thus, alluding to circumcision on the eighth day of a child's life as an argument for the first-day festival, he says:-- "It is possible for us to show how the eighth day possessed a certain mysterious import, which the seventh day did not possess, and which was promulgated by God through these rites." That is to say, because God commanded the Hebrews to circumcise their children when they were eight days old, therefore all men should now esteem the first day of the week more honorable than the seventh day, which he commanded in the moral law, and which Justin himself, in chapter xix., terms "the memorial of God." In chapter xxvi., Justin says to Trypho that-- "The Gentiles, who have believed on him, and have repented of the sins which they have committed, they shall receive the inheritance along with the patriarchs and the prophets, and the just men who are descended from Jacob, even although they neither keep the Sabbath, nor are circumcised, nor observe the feasts." And in proof of this, he quotes from Isa. 42, and 62, and 63, respecting the call of the Gentiles. Upon this (chapter xxvii.), Trypho the Jew very pertinently asks:-- "Why do you select and quote whatever you wish from the prophetic writings, but do not refer to those which expressly command the Sabbath to be observed? For Isaiah thus speaks [chap. 58:13, 14], 'If thou shalt turn away thy foot from the Sabbath,'" etc. To which Justin makes this uncandid answer:--
