Ephesians 4:5

One Lord (ei Kurio). The Lord Jesus Christ and he alone (no series of aeons). One faith (mia pisti). One act of trust in Christ, the same for all (Jew or Gentile), one way of being saved. One baptism (en baptisma). The result of baptizing (baptisma), while baptismo is the act. Only in the N.T. (baptismo in Josephus) and ecclesiastical writers naturally. See Mark 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.
