The Book of the Resurrection of Christ by Bartholomew the Apostle 21

1Then Peter said unto Thomas, 'O my brother, the invited guest to the marriage of my Lord Jesus the Christ, I say unto you, O our brother, that our Lord Jesus hath shewn Himself to us since thou didst depart from us, having risen from the dead, when as yet He had not departed, until He departed. He gave unto us His peace, and we saluted (i.e. kissed) Him, and He blessed us, and departed into heaven from us. He said to us, "I am with you at all times, I and My Father, and the Holy Spirit."'
2And when the blessed Apostle Peter had said these things [to] Thomas, Thomas grieved exceedingly, and he wept many tears, saying, 'So then, O my Lord, having raised Thyself from the dead, Thou didst shew Thyself to the Disciples. As for me, Thou didst separate me from my brethren, [for] Thou didst not wish to shew Thyself to me …
3[…] so that I might see Thee before Thou didst depart to [Thy Father].

For I cannot believe that He will rise [from the dead] and not shew Himself unto me. Moreover, He will not grieve me [by such an act], for He said to us, "I will not separate you from one another; but one and the same inheritance shall be unto each one of you in My kingdom."' And having said these things in the presence of the eleven disciples, Thomas the Apostle wept. Then the Apostles answered in the presence of Thomas saying, 'O our lord brother, be not an unbeliever concerning the resurrection of our Saviour, but believe that He hath risen, and hath departed to His Father. And we are the first unto whom He shewed Himself, and Mariham His mother.' And again Thomas answered, saying, 'I believe that He hath risen, and He is the Deathless One, for He tasted death for the salvation of us all. And it was because of [my] great grief that I doubted …'
