At my parish we recently celebrated the Great Vespers for the Feast of St. Andrew, the First Called. The local Roman Catholics attended with their Monsignor, a monk and a Maronite deacon. We shared a fasting meal together afterwards. It was, frankly, wonderful. We will be celebrating the Feast of St. Peter with them in June.
That sounds wonderful - very prayerful, very much in the spirit of faith. I am always encouraged to hear of people uniting in acts of charity or worship, and always so disillusioned by hearing people being angry and sniping.
