Luke 16

Luke 16:11

""Therefore if you have not been faithful in the [use of] unrighteous wealth, who will entrust the true [riches] to you?"
Does Luke 16:9-13 contain a contradiction regarding serving mammon?

It is sometimes argued that this passage offers a contradiction, under the presumption that the first verse is equal to serving mammon, which it is not—it refers to the use of mammon, not serving it. The Greek indicates that the commitment to either God or money is of "service" equivalent to total service, even enslavement (cf. John 8:33). This is obviously not the same as mere use.
