I can't help but think that this person is being like the Pharisees, who couldn't see the forest for the trees. They challenged Jesus because His disciples took, cleaned and ate some grain from a field they walked through on a Sabbath. They were quite hungry and were taking it for food, not for harvest. The Pharisees, however, claimed that Jesus allowed His disciples to work on the Sabbath.
|Jesus and the Pharisees|
Jesus reminded them that there are exceptions to laws. In this case, when a person needs something very much, God's love is more important than His law. The Pharisees were hyper-focused on the "rule" or the "law", such that they didn't see the bigger picture, which in this case is charity to a fellow Christian.
In my example, my friend could not extend himself by missing his Bible study to bring me to the bus stop. I may be off in my judgment of him, but even so, my idea is still valid. We all know many Catholics who can not see the forest for the trees. They are the Pharisees among us today. I know, because, at times, I am one of them.
"Oh, Dear Jesus, please give me the grace to see clearly,
so that I may imitate You more closely."
