Father Gregory Hogg helped me along a bit with this quote:
"One hears that, in foreign lands, people are now learning to swim, lying on the floor, with the aid of equipment. In the same way, one can become a Catholic or Protestant without experiencing life at all--by reading books in one's study. But to become Orthodox, it is necessary to immerse oneself all at once in the very element of Orthodoxy, to begin living in an Orthodox way. There is no other way."--Fr. Pavel FlorenskyThat last sentence is a bit of understatement, isn't it?
By the way, Father Gregory has begun his own blog, "Pillar and Ground of Truth" -- and his "On using the Fathers" gives sage advice for all of us.
When it comes right down to it, the best witness is most often "Come and see," isn't it?
