There is something special about St. John. He was the only one who was not married, the only one who was not martyred and the only one who was at the foot of the cross. There is also that very interesting apparition at Knock, Ireland, on which he is present with the Blessed Virgin and St. Joseph.
I am glad that he is my namesake.
Not sure about the tradition of St. John being the only unmarried apostle. Do you know the saint or tradition behind this assertion? Nothing in Holy Writ suggests that Andrew was married, or Matthew.
