No, it is not. When God used the term "good," he was not making an inference as to the nature, or morality of man, as you do here Reverend. You're wrong, you should admit it, and explain it as such to your congregation.
Yeah he's wrong of course; but he shouldn't have to admitt it to his comgregation.
If he has a congregation: they are only there out of choice, and it's obvious they like his message or they wouldn't be there in the first place.
When these self deluded people stand before "Jesus" at the Judgement, they will have to answer for themselves; and blaming this pastor will be a sufficent excuse!
