What is lacking is the historical context. Your source also fails to make clear that the homilies were directed against Judaiziers (Christians who followed the Law), and not the Jews.
As the brief introduction below indicates, there was a sudden resurgences in the Sabbaterianism in Antioch to which +John Chrysotsom's anger was directed.
The importance of the city and the temple for judaizing Christians during this period can be seen in the interpretation of prophetic texts that speak of the return of the Jews to Jerusalem.
Commenting on Isaiah 35:10, “the ransomed of the Lord shall return and come to Zion with singing,” Jerome says that the “Jews and our Judaizers” interpret this text to refer not to the “advent of the Savior” but to the second coming, when the Jews will enter Zion with gladness.
Similarly, commenting on Zachariah 14:10–12, “Jerusalem shall be inhabited for there shall be no more curse,” he observes that the Jews and judaizing Christians say that this refers to the building of the city and a time when “circumcision will be practiced, sacrifices offered, all the precepts of the Law observed, so that Jews will no longer become Christians but Christians will become Jews” (Comm. in Zach. 14:10).
Your source alleges that there is no good reason to explain +John Chrystostom's homilies. Out of context, as stfassisi's link (Post #5) indicated, it is indeed difficult to understand what motivated him.

Looking for reason or motivation is only done to excuse his words. John does not in any way exhibit or demonstrate the chesed (lovingkindness) As you noted there was a resurgence of following a worship as commanded by YHvH. John was angry because the believers in Antioch wanted to worship YHvH as He has commanded them. John wanted them to reject YHvH and instead embrace the Paganism of Constantine's Roman church. I recommend that you avoid the "spin" and read the words of John Chrystostom Saint John Chrysostom (c.347-407) : Eight Homilies Against the Jews Reason or motivation aside, John is vehemently and rabidly anti-semitic.

and judge John on his own words without the spin.
