Thomas wanted to see as the fellow disciples of Jesus had seen. I don't think we can blame Thomas for his wish and in so wishing/acting he demonstrated the true bodiliness of the crucified, now risen Jesus. (An important theme for the Spirit speaking through St John.) However, Thomas missed out on something less tangible but most important for all who would come later. Thomas missed out on being the one of the disciples who would believe without having seen and hence become -even if for the short time - one of the fathers (St John being the other) of all those that have not seen and yet have believed. This not-seeing state of faith is the one we live within for this time as expressed by J. R. Peacey (1896-1971) in these words: O Lord, we long to see your face, to know you risen from the grave; But we have missed the joy and grace of seeing you, as others have. Yet in your company we'll wait, ...
we look not to the things that are seen but to the things that are unseen --Paul, Apostle to the Gentiles
