Married people pledge love for each other throughout eternity. Well, now, that is easy enough but does not mean very much, for if one is finished with time one is probably finished with eternity. If, instead of saying "throughout eternity," the couple would say, "until Easter, until next May Day," then what they say would make some sense, for then they would be saying something and also something they perhaps could carry out.
