And yet he walked through walls. And yet he didn't appear as himself when he talked with others, they didn't recognize him. They spent the whole day walking and talking with him, and not until the evening until he broke bread with them to they know it was Jesus. He went up from the ground into heaven. And so forth.
Now while one can say there was some "appearance" of Jesus in some fashion or another, clearly this was not a resuscitated corpse. Human bodies don't appear and disappear. They don't walk into rooms through locked doors. They don't change their appearances. They don't levitate. And furthermore, Paul claims to have seen the risen Christ, but that was not a corporeal form. He saw Light and heard a voice. That is not a body walking around after having be revived out of a state of death.
Early Christians debated amongst themselves exactly in what way was Jesus resurrected. These are a few of the reasons they would have.
Clearly, it is spiritual in nature primarily. So what I said about applying ideas of historic fact to something like this, which would be pertinent if were are talking about a purely material reality, is a bit short sighted and missing the actual point, which is about faith, not facts.
