Luke 1:4

(sup.) Or it may be, "That thou mightest feel certain and satisfied as to the truth of those things which thou hast heard, now that thou beholdest the same in writing."

The promise was not to explain the meaning of certain new and strange things to Theophilus, but to set forth the truth of those words in which he had been instructed; as it is added, That thou mightest know the truth of those words in which thou hast been instructed; that is, "that thou mightest be able to know in what order each thing was said or done by the Lord."

For frequently, when a thing is asserted by any one, and not expressed in writing, we suspect it of falsehood; but when a man has written what he asserts, we are the more inclined to believe it, as if, unless he thought it to be true, he would not commit it to writing.

When he says, It seemed good to me, he does not deny that it seemed good to God: for it is God who predisposes the wills of men. Now no one has doubted that this book of the Gospel is more full of details than the others; by these words then he claims to himself, not any thing that is false, but the truth; and therefore he says, "It seemed good to me, having investigated every thing, to write." Not to write every thing, but from a review of every thing; "for if all the things which Jesus did were written, I do not think the world itself could contain them." (John 21:25.) But purposely has Luke passed by things that were written by others, in order that each book of the Gospel might be distinguished by certain mysteries and miracles peculiar to itself.

(Photius, comment. in Luc.) The whole Preface of this Evangelist contains two things; first, the condition of those who wrote Gospels before him, (Matthew and Mark for example;) secondly, the reason why he also himself proposed to write one. Having said, "attempted," a word which may be applied both to those who presumptuously engage upon a subject, and those who reverently handle it, he determines the doubtful expression by two additions; first, by the words, Of things which have been fully accomplished among us; and secondly, As they handed them down to us, who were eyewitnesses from the beginning. The word handed down seems to show, that the eye-witnesses themselves had a commission to transmit the truth. For as they handed it down, so it became others also receiving it in due order, in their turn to publish it. But from the not depositing in writing what had been delivered, several difficulties through lapse of time sprang up. Rightly then did those who had received the tradition from the first eye-witnesses of the Word, establish it in writing for the whole world; thereby repelling falsehood, destroying forgetfulness, and making up from tradition itself a perfect whole.
