[... Jesus also appeared after the Resurrection in places and forms as He willed – sometimes being known, sometimes not, sometimes in the open, sometimes in closed rooms, etc.

Thus I make no presumptions about the resurrection body concerning space, time (dimensions) – or mass:
----------------
So also [is] the resurrection of the dead. It is sown in corruption; it is raised in incorruption: It is sown in dishonour; it is raised in glory: it is sown in weakness; it is raised in power: It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body. And so it is written, The first man Adam was made a living soul; the last Adam [was made] a quickening spirit. – I Cor 15:42-45 ...]

Fleshy bodies and Spiritual bodies is/are quite a subject..
Seems that Paul got more of a "Vision" about these things than the other Apostle's did.. (during his conversion and grooming) and no doubt a few other things as well..
Pauls ministry seemed/seems to be more rounded in knowledge of spiritual things.. as far as I can see..
