Baptizatur Christus, et sanctificatur omnis mundus : et tribuit nobis remissionem peccatorum : aqua, et Spiritu omnes purificamur.
O, I wish I were in Ithaka for this. I saw a small island between Kefalonia and Ithaka on which was built, amidst the olive trees, a small chapel. Apparently on Theophany Even the Bishop comes thither from the mainland to bless the sea using the old Greek rite. I imagine once upon a time the Bishop of Rome blessed the Tiber in like fashion on the same day, using a similar rite; that is before the disruption of a false kalendar and the blessing of water meant something more than just a "sacramental."
