Feast of Saint Luke, Evangelist

Since, indeed, many have attempted to set in order a narrative of the things that have been completed among us, just as they have been handed on to those of us who from the beginning saw the same and were ministers of the word, so it seemed good to me also, having diligently followed everything from the beginning, to write to you, in an orderly manner, most excellent Theophilus, so that you might know the truthfulness of those words by which you have been instructed.
