Ye were free from righteousness - That is, in your former state, you were not at all under the influence of righteousness. You were entirely devoted to sin; a strong expression of total depravity.

The argument which is implied here rather than expressed is, that now they ought to be equally free from sin, since they had become released from their former bondage, and had become the servants of another master.
