Well, from what I remember from my studies, Canon Three of the Council in Trullo speaks about the need to make “pure and blameless ministers, worthy of the spiritual sacrifice of the Great God”. But, I also remember that the interpretation in the East was always “the celibate priesthood of the West and the married priesthood of the East do not contradict each other”. Also, it has been our holy tradition fro the past 2,000 years that married priests must not indulge in marital sex 24 hours before serving the Divine Liturgy. Now, depending on how often they serve…
Also, it is a simple fact that many married priests serve for years and during that time quite a few children of theirs are born. As no bishop makes any fuss of it, we tend to believe the continency, or rather fasting from marital life, has been properly kept, always 24 hours before the Divine Liturgy, plus every Friday not-withstanding.
We also had a few married bishops, and we eventually ruled them canonical, but stopped it as soon as we could. I remember the Roman Catholic Church had a few married bishops in the 20th century as well…
Anyway, personal opinion: our Lord does not care. Or else he would have hand-picked twelve young virgin boys along the lines of St. John Evangelist rather than married mature men along the lines of St. Peter.
In Christ,
