NOTES for Mat 22:34-40
It is not hard to imagine the mixed state of the Pharisees after Jesus forced the Sadducees to be silent: the One with whom they were used to arguing had put their opponents to shame. For that reason the lawyer's question about the two greatest commandments looks like a kind of probing: could He perhaps be drawn over to their side? It is hard for the Pharisees (and not only for them) to grasp that in fact they should have made the decision to cross over to His side. Moreover, even today many ideologues cannot resist the temptation to present Christ as their predecessor and like-minded ally; they too want to recruit Him into their camp. But what looks coherent in propaganda articles falls apart when it meets Reality.
And so Christ answers the Pharisee's question. But in doing so He does not simply give an answer to this particular question; He reveals the central foundations of faith and life. It is understandable that He named the words about love for God, absorbing all one's strength and aspirations, as the greatest commandment. However like it He called the commandment about love for the human person, which may have seemed strange to people accustomed to placing religious concepts above everything human. And yet this is exactly what Christ brought to people and what sets Christianity apart from all religions.
Of course, the commandment to love people is not equal to the commandment to love God; it is only like it. But in Christianity the human person is raised as high as no teaching raises him. And only Christ finally destroys the impassable barrier between God and people.
