There was once a Christian that was attending seminary that felt unusually bold one Sunday morning. He decided to go to a random church that he had never attended before. He went to the service and sat in one of the pews. Upon sitting the pastor got up and began his sermon. From the first sentence the seminary student knew that he had made a mistake.
The pastor began his sermon, "It does not matter what your religous belief is...you are all true! You will find no judgement here!"
He went through his entire sermon explaining why all religions are "true".
Following the sermon, the seminary student wanted to make a quick exit from the church. But alas...the pastor was standing at the exit, bear hugging all of the members of the church as they left.
As this man tried to leave the pastor stopped him.
"Well, my son, where are you from?"
"I am on vacation from seminary"
"Very good!", said the pastor. "What did you think about the sermon today?"
"Well I would prefer not to say for fear that I may offend you", said the man.
"Don't worry, my son! You will not offend me. Whatever your religous beliefs, they are welcome here!"
"Ok" said the man. "After hearing your sermon....well pastor...I believe you are going to hell."
After hmmm/hawwing the pastor acknowledged that maybe all religious views were NOT all true. He could not acknowledge that he was going to hell, after all!!!
The moral of the story is that there CANNOT be an ABSOLUTE religious belief that includes all people. Truth is truth. By definition, truth can only be one or the other. Either 2+2=4 is TRUE for all people at all times, or it is not TRUE.
By definition, truth cannot be 2 or more different ideas. If someone was to say, "There is NO absolute truth"...well that is a self defeating statement. You can ask, "Are you absolutely sure that is true?"
There MUST be 1 truth in all areas.
