Chapter 7 — Part I — Article V (Of the Resurrection)
Section 221. Q. How was it known that Jesus Christ had risen? A. The soldiers who watched his sepulchre knew this with terror, because an angel of the Lord rolled away the stone which closed his sepulchre, and at the same time there was a great earthquake. Angels likewise announced the resurrection of Christ to Mary Magdalene and some others. Jesus Christ himself on the very day of his resurrection appeared to many: as to the women bringing spices, to Peter, to the two disciples going to Emmaus, and, lastly, to all the Apostles in the house, the doors being shut. Afterwards he oftentimes showed himself to them during the space of forty days; and one day he was seen of more than five hundred believers at once. 1 Cor. xv. 6.
