Leviticus 20:13

Sherlock is a struggling man found refuge in being a priest, slowly discovering that his life ahead held nothing but stagnation and repetition. However with the appearance of John Watson, he discovers that maybe he isn't the loneliest man on Earth. As their relationship grows into something dwindling onto sin, Sherlock finds that he must chose between the promises he's made to God and the ever tempting heart of the lonely John Watson.
