What is meant by the saying that ‘Outside the Church there is no salvation?’
The saying “Outside the Church there is no salvation” (extra ecclesiam nulla salus) comes from St Cyprian of Carthage, who writes that “there can be no salvation for anyone except in the Church” (St Cyprian, Letter to Jubaianus, 73 [72], 21).
This teaching means that only by being united to Christ Jesus can a person be saved, delivered from eternal loss, as the Scriptures testify, applying Psalm 102 (101 LXX) to Jesus: “You, Lord, in the beginning laid the foundation of the earth, and the heavens are the works of your hands. They will perish, but you remain… you are the same, and your years will not fail” (Heb 1:10–12; see Q230). Union with the Church is union with Christ, for the Church is his Body.
Even as Moses led his people through the Red Sea before it collapsed upon “those who are perishing” (2Co 4:3), so only the greater Moses, Christ the Lord, can lead his people into the age to come, when “the heavens will pass away with a rushing noise… and the earth and the works in it will be burned up” (2Pe 3:10). Of this type the Apostle writes: “Our forefathers were all under the cloud: all passed through the sea; and they were all baptized into Moses in the cloud and in the sea. They all ate the same spiritual food and drank the same spiritual drink. They drank from a spiritual rock that followed them, and that rock was Christ” (1Co 10:1–4; see Q287). Another type of salvation and baptism is Noah’s ark (Gen 6–9): “in this ark, a few (that is, eight souls) were saved through water” (1Pe 3:20–21; see Q171, Q287). As the ark alone rode the flood, so the Church is the ark of salvation.
According to the Scriptures, to share in this salvation we must be members of Christ, that is, of his catholic Church (Eph 5:23; see Q315). Though God may, by a sovereign act, unite a person to the mystery of “Christ and the Church” in ways known to himself (Eph 5:32; Luk 23:43, the thief on the cross; see Q589, Q118), the assured and divinely appointed way to make our calling secure (2Pe 1:10) is visible union with the Church, through the Mysteries which seal our union with the divine Savior. We may say where the Church is; we are not appointed judges of where God’s mercy is not.
This assurance brings peace in the Holy Spirit, according to the will of God the Father: “Whoever has the Son has life… I have written these things to you who believe in the Name of the Son of God, so that you may know that you have eternal life” (1Jo 5:12–13; see Q484).
