Luke 24:35

For He did not show Himself to all at the same time, in order that He might sow the seeds of faith. For he who had first seen and was sure, told it to the rest. Afterwards the word going forth prepared the mind of the hearer for the sight, and therefore He appeared first to him who was of all the most worthy and faithful. For He had need of the most faithful soul to first receive this sight, that it might be least disturbed by the unexpected appearance. And therefore He is first seen by Peter, that he who first confessed Christ should first deserve to see His resurrection, and also because he had denied Him He wished to see him first, to console him, lest he should despair. But after Peter, He appeared to the rest, at one time fewer in number, at another more, which the two disciples attest; for it follows, And they told what things were done by the way, and how he was known of them in breaking of bread.

(de Con. Ev. l. iii. c. 25.) It had been already reported that Jesus had risen by the women, and by Simon Peter, to whom He had appeared. For these two disciples found them talking of these things when they came to Jerusalem; as it follows, And they found the eleven gathered together, and them that were with them, saying, The Lord is risen indeed, and hath appeared to Simon. (ut sup.) But with respect to what Mark says, that they told the rest, and they did not believe them, whereas Luke says, that they had already begun to say, The Lord is risen indeed, what must we understand, except that there were some even then who refused to believe this?
