This I always think is my reading, because it is about doubting Thomas or perhaps, as we were told at Mass, it should be “believing” Thomas for his wonderful statement – My Lord and My God. Jesus is right: “Happy indeed is the man who believes without seeing.”
I don’t have that certainty but seeing is not just with the mind’s eye. When John enters the tomb, “He saw and he believed.” It wasn’t necessarily that he saw anything much with his eyes except an empty tomb which could be explained away but that he saw in the sense of understanding.
I see the point at last of what somebody has been telling me all along. So we don’t have to see concrete physical evidence, we can see and understand and believe that way, we can see the argument or even more so the inevitable conclusion of what we have been told. Perhaps I am and many of us are at that stage. By Monday, sadly, the Resurrection studies are at an end but we have instead Nicodemus.
