Christ’s third appearance was to Simon Peter sometime before Jesus entered into the Upper Room where the disciples were assembled on Resurrection Sunday evening:
Luke 24:33-35 ...
And they [Cleopas and an unknown disciple] rose up the same hour [from eating with Jesus] and returned to Jerusalem, and found the eleven [including Simon Peter] gathered together, and them that were with them [the other disciples with the eleven], saying [to Cleopas and an unknown disciple], the Lord is risen indeed, and hath appeared to Simon[Peter]. And they [Cleopas and an unknown disciple] told what things were done in the way, and how he was known of them in breaking of bread.
