Did Jesus appear to everyone at the same time?
Did they all recognize him right off the bat?
One person thought he was a gardener. Two other people thought he was a random guy walking on the road. These were all people who had followed him faithfully in person for an extended period of time. But he didn’t permit them to recognize him from the get-go… and when they were allowed, it was unmistakable.
Mother Teresa once said:
Ven. Maria de Agreda once postulated that Jesus’ appearances after the Resurrection were ordered according to who had contemplated/dwelt upon his death and passion. The ones who had contemplated and dwelt upon it the most were the ones who he appeared to first, and going on down the line. Presumably, he never appeared to, say, Caiphas or the other leaders who had plotted his death. The appearances gave grace and courage to his followers, who were in fear of their lives, and if you read Acts of the Apostles, pretty much all of them (minus John) ended up with the courage to give witness to the Resurrection with their lives. (As an aside, I heard a cute story the other day… some guy said that Watergate led him to Christianity, when he saw how much difficulty such a small group of people had in keeping their stories straight in the face of difficulty— no one being willing to sacrifice themselves and their careers to maintain a lie.)
But it might be helpful to put those tidbits together… (a) the need to contemplate Jesus’ life, death, and resurrection, in order to “find” him; and (b) the knowledge that he’s already told us he is present in the Eucharist and in those around us. By the time you get to that point where you’re aware of his presence, it doesn’t really matter so much that you can’t put your hand in his side, a la Thomas. You’ll discover that you encounter God’s hand in your life so many times, at so many different moments, that you’ll probably lose track. Because people who seek will find, so make sure you’re seeking where he’ll be found.
