I for example "believe" that there was a FIFTH and SIXTH James (Jacob) too. It was a very popular name at that time, even if the Bible does not say it.
I remind you that you did not answer my question.
You said - The Bible is the rock solid foundation of everything we believe.
My question was:
Do you believe that the Church is "the pillar and ground of the truth" (1Tm:3:15)?
The church is the body of people who believe Jesus Christ is their Saviour. But human beings don't produce "the Truth". Truth comes from God.
