{One Lord} (heis Kurios). The Lord Jesus Christ and he
alone (no series of aeons). {One faith} (mia pistis). One act
of trust in Christ, the same for all (Jew or Gentile), one way of
being saved. {One baptism} (hen baptisma). The result of
baptizing (aptisma), while aptismos is the act. Only in the
N.T. (aptismos in Josephus) and ecclesiastical writers
naturally. See  Mr 10:38 . There is only one act of baptism for
all (Jews and Gentiles) who confess Christ by means of this
symbol, not that they are made disciples by this one act, but
merely so profess him, put Christ on publicly by this ordinance.
