We understand that God is known by many names as He is unlimited. Thus God is known by various faiths as Krishna, Yahweh, Jehovah, Allah, etc. Now according to the Vedic scriptures the age we live in is called Kali Yuga and is a fallen age of quarrel and hypocracy. In religion there are so many divisions and falsities. The real religion, - devotional service to God is practically forgotten.
Real religion is taken as irreligion, and irreligion is taken to be religion.
When the actual Truth is put forward it is blasted by nonbelievers to be nonsense. As in the case of Lord Jesus, the priests and many of the people who thought they were doing the law of God, opposed Jesus. The Old Law was set forth by Moses in the commandments, spoken to him directly by God, and now Jesus was coming and speaking of something which was apparently contrary to this. He was accused of heresy. The people could not understand the higher teachings of the Supreme Godhead, and thus they crucified Jesus thinking him to be a blasphemer.
