This is rather an old thread that has been raised from the dead, but it is always good news.
There are other Orthodox in Pakistan and it isn't clear to me if the thread means that Father John is the first Pakistani Orthodox priest, since he is not the first Orthodox priest in Pakistan. I tried to follow the link provided but it was dead. Is there more recent news elsewhere?
I was recently with Met. Nektarios, and, although we didn't talk much about Pakistan, my impression was that Fr. John was the first of several native men that His Eminence has ordained. His Eminence has also just managed to get the Divine Liturgy of St. John Chrysostom translated into Punjab, which the people on both sides of the border prefer to worship in.
