This parable is classic Jesus and stands as a warning to the critical spirit that lives in us and can take over if not combated. And it is entirely consistent with the biblical warning to beware the self-righteousness that can become the foundation of our identity.
This parable provides us with a classic example of finding a (false) identity by not being someone else. (vv 11-12) The Pharisee, critical of others, is grateful that he isn't a sinner like ... (See Phil 3:4-11) And finding one's (false) identity isn't much better if it is found in one's own righteousness. And even if a sense of righteousness isn't accompanied by a conscious rejection of others, the rejection is there by implication. And some people internalise either criticism by others or the righteousness of others. Their identity of self-rejection is formed not by the God who redeems but by the criticism and/or self-righteousness of others. Whatever the case, these identities are all false.
Imagine a society built on the Pharisee of this parable, where identity is formed and maintained by self-righteousness and criticism of others. It would be a burden because a false identity that needs to pull others down or needs to puff oneself up is like a drug and can never be fully sated. Such a society would eat itself in a flurry of criticism, self-righteousness, and virtue signalling. (Gal 5:13-15)
The sinner in the parable has a different foundation. He looks to God, the God who forgives and does not rely on the criticism of others or any alleged personal virtues. He looks to personal transformation. Imagine a society built on this foundation. It would be a society that builds up rather than pulls down. (1Thess 5:11) Inner change, not just thinking everyone else is the problem. This is (part of) what we are called to be as church. Our foundation is Christ, the one who died as a victim of just such criticism and self-righteousness. We look to personal transformation (new covenant, the law written on our hearts) and bearing one another's burdens (Matt 11:28-30; Gal 6:2-3), not adding to the burden.
