This issue is really bothering me such that I am unable to sleep. A very popular comedian has been invited to my church to perform this morning and I find it very disgusting that God's altar will be desecrated by allowing him share the same rostrum with my pastor.

Even though no gate fee is being charged, I believe that it is against the principle of our Lord Jesus Christ to reduce the church to a place of entertainment and feel good. While growing up, Sunday services used to be very 'hot' such that the impact of the message will be on all thru the week days. But now, the reverse is the case.
I want objective and scriptural contribution from my brethen. Is this practice scriptural or not?

It's all business... your pasitor is a business man

No fee is being charged, it is free of charge.

There is nothing wrong in it as long as there is no lewd comedy.
