Questioning is not trashing. If something is true, it should stand questioning. As you can see, not even believers agree on theology.
Even before one gets to disagreeing believers there are the Gospels that clearly conflict. yet we are told they are the infallible inspired words of God derived through the workings of the inward Holy Spirit... so where did the errors come from?
Scripture shows neither God or Holy Spirit can positively nail down when Jesus was born...one Gospel puts it around 4 BC and another in 6 AD.
