Baptized into Christ, may either be understood of receiving the sacrament of baptism; which who receiveth, is not only baptized in the name of Christ, and into the profession of Christ; but is sacramentally, or in a sign, baptized into Christ; or else (which, considering what followeth, seemeth much more probably the sense) it may signify a being not only baptized with water, but with the Holy Ghost and fire. Of those thus baptized, he saith, that they had put on Christ; they had accepted of and received Christ for their justification, and for their sanctification. We have the like phrase, Romans 13:14.
