Ephesians 4:5

one Lord Jesus Christ; Possessor and Prince of all His people equally.

one faith Is "faith" here the "Christian creed," or "trustful acceptance" of Christ, "saving faith"? Probably the latter, in view of the great rarity of the former meaning of the word in St Paul (Galatians 1:23; Philippians 1:27; present perhaps the best cases, and even these are not quite clear). The words here thus mean, "one and the same way of access to and union with the One Lord."

one baptism The one Divine Seal upon the one God-given faith in the One Lord. This holy Seal is "one" in respect of the Unity of the Triune Name (Matthew 28:19) "into" which, and which alone, all partakers of the covenant of Christ are baptized. The "one baptism for the remission of sins" is baptism into that Name, or into its equivalent (Acts 2:38), the Name of the Son of the Father and the Giver of the Spirit.
