Luke 1:3

St. Luke hereby explains to us the source of his writing; seeing that what things he wrote, he gained not from report, but had himself traced them up from the beginning. Hence it follows, It seemed good to me also, having carefully investigated every thing from the very first, to write to thee in order, most excellent Theophilus.

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.

(sup.) Theophilus means, "loving God," or "being loved by God." Whoever then loves God, or desires to be loved by Him, let him think this Gospel to have been written to him, and preserve it as a gift presented to him, a pledge entrusted to his care.

He writes to Theophilus, a man probably of some distinction, and a governor; for the form, Most excellent, was not used except to rulers and governors. As for example, Paul says to Festus, Most excellent Festus. (Acts 26:25.)

(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.
