{By baptized} (aptisai). First aorist middle
(causative), not passive, Get thyself baptized (Robertson,
_Grammar_, p. 808). Cf.  1Co 10:2 . Submit yourself to baptism.
So as to apolousai, Get washed off as in  1Co 6:11 . It is
possible, as in  2:38 , to take these words as teaching baptismal
remission or salvation by means of baptism, but to do so is in my
opinion a complete subversion of Paul's vivid and picturesque
language. As in  Ro 6:4-6  where baptism is the picture of death,
burial and resurrection, so here baptism pictures the change that
had already taken place when Paul surrendered to Jesus on the way
(verse  10 ). Baptism here pictures the washing away of sins by
the blood of Christ.
