You are an important leader of the church and an archon of justice.
You gain one additional domain, spell per day, of any level that you can cast. In addition, choose one permutation of detect chaos/evil/good/law. A servant of a true neutral god may choose two. You may now cast this spell at will.
Lastly, when casting inflict spells increase the damage dealt by your Strength bonus (if any) and when casting cure spells increase the damage healed by your Charisma bonus (if any). Your Strength bonus and Charisma bonus may exceed the normal maximum of the spell.
Special: Each church has its own rituals and rites regarding the archon of justice. You and the DM should work out the specific requirements (go on a quest, endure a week without food, etc.). In addition, some churches have only one archon and someday someone is going to want your job.
The archon of justice has many mundane responsibilities as well, from overseeing festivals and religious celebrations to maintaining the records, churches and shrines of his faith. The archon is responsible primarily to his faith and god.
