Such good words from Yves Congar. Of course I had no idea who he was so thank goodness for Google.
It turns out that Father Yves Congar (1904-1995) was a French Dominican friar and a catholic priest who, apart from saying many wise things, is mostly renowned for allegedly peeing on the wall of the Holy Office. The Holy Office today deals with matters of doctrine in its aim to protect faith and morals; it was founded in 1542 to defend the church from heresy, a charge almost brought against Congar by his legalistic adversary in the Holy Office.
