There were some very good and conscientious people in the time of Jesus who criticized John the Baptist. Some found his ascetic lifestyle to be crazy. Many of these same people also whined about Jesus and how he associated with sinners and pagans. The habit of filtering reality through our own prejudices can lead us to reject things that are genuinely of God. This really isn’t faith nor is it healthy logic; it is seeking to fit God neatly into our own self-conceived and prearranged perception of reality.
What we really need to do is to become pliable in the ways of faith and let ourselves be shaped by the will of God, rather than seeking it to be the other way around. In the words of Isaiah the Prophet:
Yet, Lord, you are our father;
we are the clay and you our potter:
we are all the work of your hand.[1]
[1] Isaiah 64:7
