O ye beloved of the Lord! The Cause of God hath never had any place for denouncing others as infidel or profligate, nor hath it allowed anyone to humiliate or belittle another. Contend and wrangle not with any man, and seek ye not the abasement of any soul. Disparage not anyone's name, and wish no harm upon      anyone. Defile not your tongues with calumny, and engage ye not in backbiting. Lift not the veil from the doings of others, and so long as a person professeth to be steadfast, remonstrate not with him, nor expose him.

Let not these very words be a pretext for dispute and contention. Through your constancy and steadfastness destroy the edifice of vacillation, and by your faithful adherence and scrupulous observance, strengthen the foundations of the Cause of God. Leave the people of negligence unto themselves and refer them for judgement to the Lord of the Covenant and Testament. 
(‘Abdu’l-Baha, from a newly translated Tablet included in a letter dated April 2001 written on behalf of the Universal House of Justice to an individual believer)
