In my opinion, the Pharisees are important to consider in this day and age in the Church. I don’t say that to use the group as an epithet, nor to use an ad hominem to target bloggers I disagree with. I think we need to consider them because they did have an attitude towards religion that seemed right from a human perspective, but ultimately that attitude fell short in the eyes of God.
Briefly, the view of the Pharisee was (seeking to avoid pejorative terms) that one was faithful to God by keeping His laws. In doing so, they offered their interpretation of how the Law was best followed. People who did not follow that interpretation were considered sinners. In contrast, because they followed the Law in accordance with their interpretation, they believed they were holy. It strikes me as being an “either-or” fallacy. Either one followed their interpretation of the Law and were holy, or they did not follow their interpretation of the Law, and were corrupted. The problem is, the either-or fallacy overlooks the possibility of there being more than two options—in this case, the fact that it was not enough to follow the observance of the Law. Jesus did not fault the Pharisees for keeping the Law. He faulted them for failing to love God and neighbor while keeping the law (Matthew 23:23).
