Wellhausen considers this a variant of Lk viii, 19-21, which latter is taken from Mark (iii, 31-35). The parallelism is not very close, to say the least. While a case may be made out for the occurrence of this section in Q, as is apparently done by Mr. Streeter, it seems better to us to assign it to a special source of Luke’s.
“IF THINE WHOLE BODY IS LIGHT”
(Lk xi, 36)
If this saying were genuine, it would naturally be assigned to QLk. But the text is not well attested, and it is perhaps better to regard it as a gloss.
THE PARABLE OF THE FOOLISH RICH MAN
(Lk xii, 13-21)
Wernle remarks concerning this section that anyone with a sense for Herrenworte will recognize at once that vss. 15 and 21 are from Luke and not from Jesus. Vs. 21 is omitted in some manuscripts. The parable is from a special source.
AN EXHORTATION TO WATCHFULNESS
(Lk xii, 35-38)
This might almost be considered as a variant of Matthew’s parable of the Ten Virgins. It stands in close connection here with Q material. No more probable source can be suggested for it than Luke’s recension of Q.
