'Offender' in the Bible

For [you can look back and] see what an earnestness and authentic concern this godly sorrow has produced in you: what vindication of yourselves [against charges that you tolerate sin], what indignation [at sin], what fear [of offending God], what longing [for righteousness and justice], what passion [to do what is right], what readiness to punish [those who sin and those who tolerate sin]! At every point you have proved yourselves to be innocent in the matter.

So although I wrote to you, it was not for the sake of the offender nor for the sake of the one offended, but that your earnestness on our behalf might be made known to you in the sight of God.
