Very little about him has come down to us. John alone mentions a question he addressed to Jesus at the Last Supper: Thaddaeus says to the Lord: "Lord, how is it that you will manifest yourself to us and not to the world?".
This is a very timely question which we also address to the Lord: why did not the Risen One reveal himself to his enemies in his full glory in order to show that it is God who is victorious? Why did he only manifest himself to his disciples? Jesus' answer is mysterious and profound. The Lord says: "If a man loves me, he will keep my word, and my Father will love him, and we will come to him and make our home with him" (Jn 14: 22-23).
This means that the Risen One must be seen, must be perceived also by the heart, in a way so that God may take up his abode within us. The Lord does not appear as a thing. He desires to enter our lives, and therefore his manifestation is a manifestation that implies and presupposes an open heart. Only in this way do we see the Risen One [more].
