It should be obvious. When fellow Christians openly deride another's Christianity, particularly at a time when the Atheists and the Muslims and the perverts are attempting to overwhelm Christian faith, values, and culture, it is the work of the Devil, not Christianity.
We have tremendous work ahead of us and we have to be unified in that work or we could fail.
I expect that the Lord would be aghast at his followers focusing on nitpicking other followers instead of fighting against the tide of evil threatening the world.
Step beyond yourself for a moment here.
Imagine you are either a latecomer to this thread...or a lurker...
...and they've read now four times on this thread your referencing other Christians' expressions on this thread is either "the work of the devil" or is in "proximity" with the devil, or has "thrilled" the devil...
...can you not see how these newcomers/lurkers might wonder how you've failed to see these constant linkages of other Christians to the devil as itself "deriding"?
You see, what brought me into this thread was this constant knack you have for engaging in the very religious expression behavior your critique in others:
Simply put: You deride the religious ways others deride the religious ways of others...(but somehow your derision is to be sanctioned)
Sorry...but you either need to consider altering your own personal standards...or begin consistently applying what you do toward others...to yourself...
