Patrick,
Probably, Sir, it was their - to me at least - bizarre pre-occupation with dates. As I have said I very much liked the priest, and others in the congregation. The humour about the supposed laxity of the 'new calendarists' was quite gentle but funny. So I suppose I found a dissonance between that and the exactitude of others there.
Then I reflect on the history and the statements of some 'new calendarists, and maybe some of it is understandable. For me though the whole Greek witness regarding the Church calendar is so complex and fractured that I am left confused by the situation in Greece.
St. Paul in his first epistle to the Corinthians, says, "For other foundation can no man lay that that is laid, which is Jesus Christ." And continuing, "I have learned there are contentions among...... Every one saith, I am of Paul; and I of Apollos; and I of Cephas; and I of Christ. Is Christ divided? was Paul crucified for you?"
Among the Orthodox Greeks the situation the Holy Apostle described in that first century is replicated and more today. Each 'group' protests their 'sole' adherence to The Truth, yet if they each claim to be the sole faithful remnant how might one discern, given their uncertain histories?
