It's a pity this article doesn't offer an substantial analysis of Fr. Weinandy's letter and his very legitimate concerns; concerns shared by many faithful Catholics. 

Here's an interesting insight:

"I have often asked myself: “Why has Jesus let all of this happen?”   The only answer that comes to mind is that Jesus wants to manifest just how weak is the faith of many within the Church, even among too many of her bishops.  Ironically, your pontificate has given those who hold harmful theological and pastoral views the license and confidence to come into the light and expose their previously hidden darkness.  In recognizing this darkness, the Church will humbly need to renew herself, and so continue to grow in holiness."
