Both Tom directly (see link below), and Ryan (indirectly) make a very important point.
While I try to think with the Church at all times, there will be times that I fail. Most often I fail from ignorance, not malice; although I will not preclude the possibility of the latter.
One is wise to question everything and its authority, particularly if it is the opinion of one person before accepting it as a reasonable premise and then to test the reasoning. Mine is, honestly, not top notch. I am a contemplative first, a thinker second. As a result, some of my thought lines can be muddled.
So I guess the caution here as well as elsewhere around the Blog circuit, or even in the world at large is Caveat lector. Whatever you read, ask questions, check it out, think it through.
