Eleven different appearances of our risen Lord are recorded in the New Testament...
To Mary Magdalene at the sepulchre alone. This is recorded at length only by John (20:11-18), and alluded to by Mark (16:9-11).
To certain women, "the other Mary," Salome, Joanna, and others, as they returned from the sepulchre. Matthew (28:1-10) alone gives an account of this. (Compare Mark 16:1-8, and Luke 24:1-11.)
To Simon Peter alone on the day of the resurrection. (See Luke 24:34; 1 Cor. 15:5.)
To the two disciples on the way to Emmaus on the day of the resurrection, recorded fully only by Luke (24:13-35. Compare Mark 16:12,13).
To the ten disciples (Thomas being absent) and others "with them," at Jerusalem on the evening of the resurrection day. One of the evangelists gives an account of this appearance, John (20:19-24).
To the disciples again (Thomas being present) at Jerusalem (Mark 16:14-18; Luke 24:33-40; John 20:26-28. See also 1 Cor. 15:5).
To the disciples when fishing at the Sea of Galilee. Of this appearance also John (21:1-23) alone gives an account.
To the eleven, and above 500 brethren at once, at an appointed place in Galilee (1 Cor. 15:6; compare Matt. 28:16-20).
To James, but under what circumstances we are not informed (1 Cor. 15:7).
