Biblology as an idiom refers to things which are not scientifically verifiable. This is true about the Birth of Jesus, he being a messianic God, his ministry and performance of miracles, his death and resurrection. For a Christian believer, all these assumed to be true by faith. An atheist or a skeptic would refute all of it outright. But it is amazing that the gospel written by four different people reveal much the same thing.
Example: Biblology of the life of Christ can be resuscitated only by faith and belief and not by rationality.
Skeptics disprove Biblology.
