Eusebius of Caesarea

For the two Evangelists, that is, Luke and John, write that He appeared to the eleven alone in Jerusalem, but those two disciples told not only the eleven, but all the disciples and brethren, that both the angel and the Saviour had commanded them to hasten to Galilee; of whom also Paul made mention, saying, Afterwards he appeared to more than five hundred brethren at once. (1 Cor. 15:6.) But the truer explanation is, that at first indeed while they remained in secret at Jerusalem, He appeared once or twice for their comfort, but that in Galilee not in the assembly, or once or twice, but with great power, He made a manifestation of Himself, shewing Himself living to them after His Passion with many signs, as Luke testifies in the Acts. (Acts 1:3.)
