Understanding Necessary and Sufficient Conditions
The problem comes in, then, when an atheist says that he or she is not now a Christian. Atheists reject the very points that are necessary to be a Christian at all. But that's the rub. If you claim that you used to be a Christian, you are then saying that the concept of being a Christian can obtain. Thus, you are also saying that God does exist, that Jesus did die and rise again, and any other point that is also necessary for salvation also obtains. But at the same time, as an "ex-Christian" you are denying these very points!
As the comments on Max's article seems to show, there are a lot of people who are confused about the concept of necessary and sufficient conditions. These distinctions are crucial in clear-thinking and I found a wonderful video that pretty clearly spells them out. I hope this will help you better in your conversations.
