There is no more beautiful chapter in Scripture than John 17. Christ’s high priestly prayer is among the summits of the New Testament. It tells us about Christ’s earthly work; about His love for us; about His relationship with The Father; about intra-Trinitarian love Itself. And in this prayer, three times in eleven verses we encounter the phrase, “That they may be one” (John 17:11-22). What could this mean?
Yes, one can offer objections about unbiblical ecumenism. One can justify fragmentation between denominations by imagining one’s own grasp of the truth demands separation from those less skilled exegetically. One can argue that the true church is invisible and unity really does exist among true believers. But we can’t escape Jesus’ words in John 13:35, “By this shall all men know that ye are my disciples, if ye have love one to another.”
Know? How? Men and women who are not yet reconciled to God have a difficult time seeing an invisible church. Instead, today, they see hundreds of contentious denominations—each one (as with the fable about blind men describing an elephant) clinging to a partial, even if vital, element of the fullness of Truth.
“One body, and one Spirit . . . one hope of your calling; One Lord, one faith, one baptism, one God and Father of all” (Ephesians 4:3-6) That is the metric against which the Church is measured: unity.
From a positive perspective, what does unity mean? Unity means I am part of a Church that is in Africa, Asia, Australia, Europe, and the Americas—with indigenous bishops and priests. “Go and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: teaching them to observe all things whatsoever I have commanded you” (Matthew 28:19-20).
The Catholic Church has always gone; it has always taught; it has always baptized—starting in what we call the Middle East today (Jerusalem, Antioch, Ephesus, and elsewhere) and continuing on to Europe, the Americas, Africa, Asia, and the Pacific. The Catholic Church was there. The Catholic Church is there. It maintains a common Liturgy, so if I am there—whether in Sydney, Sao Paulo, or Köln—local believers and I will rejoice in our unity while worshipping one God and Father of all.
Without no harshness intended, protestant fragmentation is not biblical. In Ephesians, Paul writes, “Endeavoring to keep the unity of the Spirit in the bond of peace. There is one body, and one Spirit, even as ye are called in one hope of your calling; One Lord, one faith, one baptism, one God and Father of all” (Ephesians 4:4-6). Peter writes, “love one another with a pure heart fervently” (1 Peter 1:22). The writer of Hebrews says, “For both he that sanctifieth and they who are sanctified are all of one” (Hebrews 2:11).
How then, have we ended up with more versions of the Truthin the 21st century than the believers Paul chastised in 1 Corinthians 1:11-12? “Some from Chloe’s household have informed me that there are quarrels among you. What I mean is this: One of you says, ‘I follow Paul’; another, ‘I follow Apollos’; another, ‘I follow Cephas’; still another, ‘I follow Christ.’ Is Christ divided?”
Is Christ divided? “God forbid!” as Saint Paul so often wrote. By God’s grace, we follow one Lord, one faith, one baptism.
What a Church! What a biblical Church.
Certainty. History. Unity. Authority. Liturgy. Christianity Richly!
