What Do You Love, Trust, and Serve?

Rosner:

What constitutes a god? Martin Luther's answer, as he reflected on the first commandment in his larger catechism, was "whatever your heart clings to and relies upon, that is your God; trust and faith of the heart alone make both God and idol." We wish to confirm this view, but also to emphasize love and service: a god is that which one loves, trusts, and serves above all else.

—B. S. Rosner, "Idolatry," NDBT: 575.
