THIS QUESTION IS ONLY FOR REFORMED AND PRESBYTERIANS (Read as - Not Baptist, Independents, or Congregationalists). The PCUSA is universalist, allows prayer to Allah and denies Sola Christus. The Roman Catholics have the Pope who is the antichrist and proclaims a false gospel. Now my question that stems I suppose from those who say that Roman Catholic baptism is valid (not arguing that here: for or against), what does the PCUSA and the Papists have to do so that their 'baptism' that they administer is no longer valid? There has to be a point where a 'church' becomes no church at all. What is that point? WCF 25.5 says, "The purest Churches under heaven are subject both to mixture and error; and some have so degenerated, as to become no Churches of Christ, but synagogues of Satan."
