Saint John the apostle faithfully kept the seventh day Sabbath, not the Roman Sunday; Saint John the apostle faithfully kept the annual Passover, not the papist Easter, and faithfully observed the Jewish dietary laws (God gave Israel to share with all mankind) -- he didn't give folks a license to sin and pig out on whatever their dark heart coveted or to strangely engage in a cannabilistic ritual of eating blood that the APOSTLES (he was one of them) forbad converted Jews, Israelites and Gentiles at the holy Jerusalem Council of Acts 15 - and continued to keep the "Jewish festivals" the early Church of God (converted Jews, Israelites and Gentiles) kept -- not the Roman hollow days like Christmas (Saturnalia - a rose by any other name...) and the rest of the cheap replacement theology substitutes.
We need to do as the early Church of God did and keep the commandments and holy days of God -- not the idolatrous traditions of men, not the baptized paganism of Roman wolves in sheep's clothing (the Babylonian Mystery religion in Christian drag), so help us God.
Jude 1:3
Beloved, while I was very diligent to write to you concerning our common salvation, I found it necessary to write to you exhorting you to contend earnestly for the faith which was once for all delivered to the saints [in Jerusalem, not Rome].
Jeremiah 6:16
"Thus saith Yahweh, stand ye in the ways, and see, and ask for the old paths, where is the good way, and walk there in, and ye shall find rest to your souls. But they said, we will not walk therein."
