All the posters have given excellent advice…
May I bring in some personal thoughts? I’ve had several friendships with priests-they have always treated me with respect. And I respect them in their vocation, too. One of my best friends is a priest in England. He was ordained by John Paul II in 1982, during his visit to Britain. I met my friend by chance while on a pilgrimage to Fatima, Portugal in 1988.
He either writes to me [letters and postcards] or else phones. I’ve visited him twice in his parish in England (1997 and 1999), and once in London (1989). I treat him as a brother, and during the three times we have met each other, he always gave me a hug and a kiss. Our friendship is like what St. Therese had for her two ‘spiritual brothers’ Fr. Belliere and Rouland (has anyone hear read Bishop Patrick Ahern’s book, “Therese and Maurice: The Story of a Love” ? ). And no one ever accused St. Therese of being ‘in love’ with either one of those two priests!
I had another priest-friend who was from Quebec, Canada. I met him literally in St. Therese’s ‘front yard’-Les Buissonets, her childhood home in Lisieux! At the time  I didn’t know he was studying for the priesthood; but in 1993 he sent me a picture from his diaconate ordination in Italy. He was ordained in the south of France in August 1993, and I went to visit him in October of that year. I stayed with him and two other French-Canadian seminarians in a small village in the Pyrenees section of France, near Lourdes. My friend was kindness itself-he was like a brother to me, just as my English priest-friend! I could talk to him about anything! I saw him again the next year, when he was home in Canada on vacation. And there, as in France, I was very comfortable with him-there was no fear of ‘falling in love’ with either him, or with my English friend! Finally he came back home to Canada for good about four or five years ago [health reasons], and he sent me a postcard telling me the news. I don’t have his current address, so I’ve lost touch with him. But I still pray for-and yes, ‘love’, BUT IN A CHASTE WAY-both of my ‘priest-brothers’!
