The authors are Roman Catholic.
They insisted that the evidence speak for itself.
They were exhaustively thorough and meticulous.
The RCC has long dismissed the truth in favor of it’s own power-mongering fantasies.
Do these authors believe in the reality of miracles, such as at Lordes, Guatalupe, or in the Gospels? If not, then they are just atheists or pagans operating under the label of Catholic.
