Justin also stated,
For I choose to follow not men or men’s doctrines, but God and the doctrines [delivered] by Him. For if you have fallen in with some who are called Christians, but who do not admit this [truth], and venture to blaspheme the God of Abraham, and the God of Isaac, and the God of Jacob;
who say there is no resurrection of the dead, and
that their souls, when they die, are taken to heaven; do not imagine that they are Christians (Dialogue. Chapter 80).
Justin believed in soul sleep, If you don't, don't even imagine you are a Christian. Which eliminates just about every believer
To deny it, was to deny the resurrection, similar to SDA, Jehovah's Witnesses
Justin did not believe that the Sabbath was set-apart from the beginning. Genesis 2:3
he believed that it first came into existence with Moses as punishment
He left Ephesus, went to Rome where he wrote to Trypho in 140

Polycrates, an early Christian martyr, learned from Polycarp, one of John’s disciples, to keep the feasts. When Victor sought to enforce the observance of Easter, Polycrates wrote him a letter in which he lists important Christian fathers who kept
Passover, not Easter:
Therefore we keep the day undeviatingly, neither adding nor taking away, for in Asia [Minor] great luminaries sleep, and they will rise on the day of the coming of the Lord, when he shall come with glory from heaven and seek out all the saints. Such were [the apostle] Phillip. . . There is also John who lay on the Lord’s breast. . . . And there is also Polycarp at Smyrna, both bishop and martyr, and Thraseas, both bishop and martyr, from Eumenaea. . . . [Also] Sagaris,. . . .Papirius,. . . .and Melito. . . .
all of these kept the fourteenth day of the Passover according to the gospel, never swerving, but following according to the rule of the faith. (Polycrates, Letter to Victor, Bishop of Rome, quoted in
Eusebius’ Ecclesiastical History)
