I was asked by a baptist friend if the Reformed and Presbyterian churches would require a person to be re-baptized if they were baptized in a Church of Christ? My initial thoughts (I haven't replied yet) are as follows: "The short answer is yes Reformed would generally see it as a valid baptism. A valid baptism is one done in a Trinitarian formula (in the name of the Father, Son, Holy Spirit), that is also done by a church whose beliefs are within the bounds of historical Christian orthodoxy. In other words those who would affirm (I understand that COC rejects confessionalism) the doctrine's taught in the historical creeds e.g. Christ- one person two natures, one substance with the Father, and so on. So while the Church of Christ has some major faulty views (baptismal regeneration,Perfectionism, etc) not all are as extreme and many still have some semblance to that of a True Church. Whereas Jehovah Witnesses, Mormons and such are not! Any thoughts would be appreciated, thanks.
