I first visited the Holy Monastery of Esphigmenou (the tighlty girdled one) in 1968. There were only a handful of monks and I was very warmly received and since I was not married at the time, was invited to join the brotherhood. I returned in 1982 to find the monastery flourishing but very hostile to visitors who were not Greek.
However I held my peace and entered the Trapeza and received the blessing of the Igumenos. But a trial was to begin. During the evening vigil service I was repeatedly accosted by young zealots who asked what was I doing in their church. Having explained numerous times I was Orthodoxos, I resulted to ignoring their questions and signed myself with the cross, which seemed to send them away. Eventually an elderly monk, who had been an engineer in Paris, invited me to join the monks on the kliros.
The next day, I was invited with other pilgrims for coffee after the Liturgy in the cell of the Igumenos. To my surprise it was the saintly elder Euthemios whom I had met at a skete 10 years before - but that's another story.
While I admired the Fathers stand for true Orthodoxy, I found the zeal of some of the young ones out of place. But that seems to be how life is. As you get older and may be more wiser, you are not so quick to judge.
