{Acceptable to him} (dektos aut(9369)). Verbal adjective from
dechomai. _Acceptabilis_. That is to say, a Gentile would not
have to become a Jew in order to become a Christian. Evidently
Peter had not before perceived this fact. On the great Day of
Pentecost when he spoke of the promise "to all those afar off"
( 2:39 ) Peter understood that they must first become Jews and
then Christians. The new idea that now makes a revolution in
Peter's outlook is precisely this that Christ can and will save
Gentiles like this Cornelius group without their becoming Jews at
all.
