(a) Among the Jews was a group who believed that the deeds of a person, good or bad is being punished or rewarded in this life. As for the hereafter and the day of Qiyaamat, punishment and reward after death, resurrection ail these beliefs are wrong. These were the Saducees.
(b) A second group did believe in all those things of the hereafter but they also believed that for reaching to Allah (SWT) it was necessary that one should avoid worldly pleasures and the secluded from the people of this world and to live an ascetic life. Hence they preformed to live away from societies in monasteries and huts. However this group had before the advent of Nabi Esa (A) lost their position and under the ruse of having cut themselves off from the world were being involved with all worldly and dirty things Outwardly they were still appearing ascetic hermits but in their private lives they weres guilty of the most heinous sins, permissiveness and drunkenness. These were the farisees.
(c) The third group had to do with service to the Holy Temple. Their situation was such that the service which they were supposed to deliver for the pleasure of God and which was to be based upon sincerity, these services were made into a form of business and for as long as they were not paid for any services they refused to deliver. So much so that they ever went so far as to alter the texts of the Toraat. These were the priests.
(d) The fourth group were above all these others. They had gradually succeeded in lefting the general public believe that there were no basic principles of religion except those which they issued. They had the prerogative to declare the permissible things as non permissible and to declare the non-permissible things as permissible. They could add to the religion and discard from it. They had the right to write for someone a pass to enter paradise and for whomsoever they wished they could write out a certificate for entrance to hell. In other words they were among Bani Israel, "the gods other than God almighty." In the alterations of the Toraat both in words and in meaning they had become very advanced. Through all this they had been seeking to acquire worldly wealth, and for the sake of pleasing the public were prepared to change and alter the injunctions of Deen. These were the Ahbaar "Rabbis" and the scholars.
These were the various group of people and their beliefs and these were the people among Nabi Esa (A) had to carry on his mission, and for whom rectification he was sent. He first took careful notice of each ones beliefs and with sympathy and love criticised their actions, encouraging them to bring about changes for the better. He endeavoured to remove from them ail evils and to connect them once more to the Creator. However, they refused to make alternations to their evil deeds and not only that, they also started calling him 'the Maseeh of falsehood', becoming his opponents in the spread of the truth. They also made various plans against him and even were bound to seek to kill him.
