To make righteous; specifically, to justify religiously, to absolve from sin.
"The priest offered a prayer of intercession to make the sinner righteous before God."
In plain English: Righteous is not actually used as a verb; it is only an adjective meaning morally good or just.
"The righteous is not used as a verb in standard English, so no such sentence exists; you likely meant to use it as an adjective or perhaps confused it with another word like "rectify." If you need examples for the common meaning of righteous (meaning morally correct), here are those instead: She felt completely righteous about her decision. The movie portrays a righteous hero who never gives up on justice."
Usage: This verb form is archaic and rarely used in modern English; prefer the adjective "righteous" or phrases like "justify" instead. It almost exclusively appears in theological contexts regarding divine justification rather than personal moral standing.
