Only greatly insolent people establish a religious law which is to be taken for granted by others, which should be accepted by everyone on faith, without any discussion or doubts — Why must people do this?
What a strange thing! Many scoundrels try to disguise their dirty deeds by their dedication to the interests of religion, or by their high morals or by love for their motherland.
— Heinch Heine
But be not yet called Rabbi: for one is your Master, even Christ; and all ye are brethren. And call no man your father upon the earth: for one is your Father, which is in heaven. Neither be ye called masters: for one is your Master, even Christ.
— Matthew 23:8-10
The essence of the teaching of Christ is to follow his commandments. Those who just repeat, "My God, My Lord" will not get to heaven, only those who fulfill God's will.
