The earliest Christians, being converted Jews, followed the Jewish practice of observing the day on which the Paschal lamb was slaughtered at Passover, which was the 14th day of the Jewish lunar First Month, Nisan. By the second century Christians of Asia Minor kept Nisan 14, irrespective of what day of the week it fell on, thereby acquiring the name of “Quartodecimans,” later to become a term of anathema.

The paradox of a Jewish-Christian practice, traced by its adherents back to the Apostle John and acknowledged even by its opponents to be the older practice in the Church, subsequently being declared a heresy was not lost on the later Irish and English churches, in which controversialists including the 7th-c. Roman curia professed to detect residual traces of the practice. By the time Christianity reached Ireland in , Christians everywhere had agreed that Easter should be kept on a Sunday, following the 14th day of the First Month luna XIV , after the spring equinox.

These early Christians, following the practices of Greek-speaking gentiles, also supposed that pascha derived frompaschein “to suffer,” and therefore concluded that Easter denoted the Passion, rather than the Resurrection. The combination of these uncertainties with the fact that churches in Rome and Alexandria and elsewhere too differed in their methods of calculating luna XIV and the First Month, as well as the correct date of the equinox, led to the situation in which churches in different parts of the Christian world celebrated Easter Sunday on different dates.

Stark divergences in and again in between the Roman and Alexandrian cycles led Pope Leo to ask his archdeacon, Hilarus, to commission a new table, which was drawn up by the Aquitanian mathematician Victorius and published in Two advantages of his table, however, enabled it to secure widespread adherence: it was a perpetual cycle of years running from c. It is not certain which Easter cycles were introduced into the fifth-century Irish church, but it may be assumed that Palladius introduced whatever cycle was prevalent in Gaul in the s either an year cycle or an early version of the Alexandrian year “Metonic” cycle championed in the s by Ambrose of Milan , while St.

Patrick supposedly active in Ireland at around the same time as Palladius, or perhaps a generation or so later , would, in all likelihood, have introduced a form of the year Easter cycle then in use by the British church.
