Jesus distinguishes between earthly and spiritual duties: taxes to Caesar, devotion to God

Today, so to speak, God defends His own ground: He neither wants to trample on us nor allows us to trample on Him. How far does the power of “Caesar” reach? Where does the power of God begin? How troublesome we are! We would even like to draw a boundary between “me” and “God”: here is my freedom, and over there is Your Heaven… God does not want to interfere in our temporal affairs, but neither does He accept that we silence His voice… It is true, “I am free”; but it is also true that without God “I would not be free” (indeed, “I would not even exist”). —“God alone is God, and let God be God” (Benedict XVI).
