In the following quotes from Dipose's book "The Origins and Effects of Replacement Theology", he seems to reveal the basic reason why Good Friday does not end up on Passover each year. The usual explanation is that the Gregorian calendar runs different than the Jewish lunar calendar but this does not answer why not keep Good Friday connected day-wise with Passover. This tidbit from Diprose is new to me and revealing. Seeds of antisemitism from the Church Fathers?

In AD325, Constantine wrote a letter to those bishops who had not been present at the Council of Nicea concerning the date of Easter. 110The following consideration contained in this letter, “We ought not, therefore, to have anything in common with the Jews,” sums up one of the key ideas behind much subsequent legislation against the Jews. All things Jewish were understood to be totally incompatible with Christianity.p.93
The following samples of canon law show that the Church was not prepared to recognize the fact that Judaism and Christianity have much in common. According to Canon I of the Synod of Antioch (341), whoever observes Easter at the same time as the Jews makes himself “an alien from the Church, as one who not only heaps sins upon himself, but who is also the cause of destruction and subversion of many.” p.94
