Contra factum non valet argumentum (You cannot argue against facts). The fact of the Resurrection of Jesus is incontrovertible. You read the various narrations about the Risen Jesus in the Bible, the four gospels and letters of the Apostles, they tell of actual witnesses of the fact of the Resurrection. St. Paul speaks of more than 500 people seeing the Risen Christ (cf. 1 Cor. 15:1-5). Most of those saints who attested on the truth of the Resurrection sere supported by God’s assistance by the proof of many signs and miracles that served to prove the truth of what they proclaimed.
That’s the history of the belief of billions of people, in past and present history. We may just enunciate one usual expression which has already become proverbial, applying this to the fact of the Resurrection of the Lord Jesus, the Son of God and Our Savior. You can fool some of the people all the time, all the people some time, but you cannot fool all the people all the time. All those billions of believers could not be wrong in their belief of the Resurrection.
