Did Chrysostom's Sermons Prove Shabbath and Appointed Times Still Attracted Christianoi After Nicaea?

386–387 CE · Chrysostom's homilies

What the ancient record says

Yes, with one correction: Nicaea was 325 CE; his sermons came ~sixty years later, not "centuries." But the point stands, long after Nicaea, some Christianoi still participated in Yahudi observances. Across the homilies he discusses Christianoi drawn toward Yahudi fasts, festivals, synagogues, and related practices; other discussions identify Shabbath and circumcision among the practices at issue, but each exact claim should be tied to the specific primary passage before publication.

Contradicts a picture where Nicaea instantly erased all contact, history is not a switch: institutional decisions at one date, human practice continuing for generations. Strongly supported: by the late 4th century the boundary in Antioch remained porous enough that Chrysostom preached an entire campaign.

Does not prove every Christianos observed Shabbath, that every synagogue attendee agreed with every Yahudi belief, or the ancestry of each participant.
