You could just tell him this is a very complicated religion that you dont completely understand because they change thier teaching a lot!
Also Luke 12: 42 And the Lord said: "Who really is the faithful steward, the discreet one, whom his master will appoint over his body of attendants to keep giving them their measure of food supplies at the proper time? 43 Happy is that slave, if his master on arriving finds him doing so! 44 I tell YOU truthfully, He will appoint him over all his belongings. 45 But if ever that slave should say in his heart, ‘My master delays coming,’ and should start to beat the menservants and the maidservants, and to eat and drink and get drunk, 46 the master of that slave will come on a day that he is not expecting [him] and in an hour that he does not know, and he will punish him with the greatest severity and assign him a part with the unfaithful ones.
This passage does not use the word EVIL but it is implied when compared to the Mathew account. BOTH accounts seem to indicate that they are the same slave and the scenario is one, if they were doing things right and two, if they were being bad.
dont shoot him down play dumb and make him WORK....oompa
