§644

Even when faced with the reality of the risen Jesus the disciples are still doubtful, so impossible did the thing seem: they thought they were seeing a ghost. "In their joy they were still disbelieving and still wondering." Thomas will also experience the test of doubt and St. Matthew relates that during the risen Lord's last appearance in Galilee "some doubted." Therefore the hypothesis that the Resurrection was produced by the apostles' faith (or credulity) will not hold up. On the contrary their faith in the Resurrection was born, under the action of divine grace, from their direct experience of the reality of the risen Jesus.
