Yes, you are. Certainly you can debate how much a Christian should or should not give to his local church. If you are claiming one should not give to the local church you are going against the teaching of the Bible.
Where does it say to give anything to YOUR local church in the Scriptures. I'll let you in on a little secret. It doesn't. That is your choice.
Glad to see that your "pastor" has rubbed off on you to the point that his doctrine has become your doctrine. I mean... who cares if he believes anyone that gets saved goes to heaven regardless of what they do. I mean.... that is really trivial.... Geesh
