19 Now, therefore, you are no longer strangers and foreigners, but fellow citizens with the saints and members of the household of God, 20 having been built on the foundation of the apostles and prophets, Jesus Christ Himself being the chief cornerstone, 21 in whom the whole building, being fitted together, grows into a holy temple in the Lord, 22 in whom you also are being built together for a dwelling place of God in the Spirit. (Ephesians 2:19–22, NKJV)
Zealously justifying division into hundreds and hundreds of different churches with opposing doctrines, worship practices and polity, Protestant denominationalism says the church is comprised of many churches (denominations). Today’s passage shows the Scriptural futility and error of this rationale. The household of God (the church) is the “whole building” that is “fitted together” to form “a holy temple of the Lord” (v. 19-21). God has one temple, one church. God’s temple is not a collection of many temples (different denominations), it is built of “living stones” (Christians, 1 Peter 2:5). Christians, not denominations, constitute the temple in which God dwells. Instead of defending unity in moral and doctrinal diversity (which is the essence of denominationalism), we urge our religious friends to choose the divine wisdom of unity in truth (John 17:20-21). Just as God has one temple, even so there is one church that belongs to Christ to which the saved are added (Matthew 16:18; Acts 2:47). Additional churches are of men, not of God.
4 There is one body and one Spirit, just as you were called in one hope of your calling; 5 one Lord, one faith, one baptism; 6 one God and Father of all, who is above all, and through all, and in you all. (Ephesians 4:4–6, NKJV)
Of this passage, David Whitehead, Senior Pastor, GraceNYC.org, wrote, “even though there may be variations of Christian belief, they are all tethered to one hope, Jesus Christ. This means that the church should be a place of unity with diversity” (theDailyBibleVerse.org). Faith, he says, is expressed in different ways, even as that faith comes from one source. Surely, he must know that one source of faith does not produce different expressions of faith, any more than one source of water yields both fresh and bitter water (James 3:11). Whitehead continues, “the day will come when that source will call us together” (Ibid.). The apostle Paul is not describing an aspirational anticipation of future events. He is describing the present reality. Far from this being an endorsement of ecumenical “unity with diversity,” it is a bold declaration of the platform of truth upon which we are “endeavoring to keep the unity of the Spirit in the bond of peace” (Ephesians 4:3). Unity in Christ has one body, one Spirit, one hope, one Lord, one faith, one baptism and one God and Father of all. Without this platform of truth in place, unity in Christ does not, and will not, exist – even when diversity is excused, and even celebrated.
By Silvanus, our faithful brother as I consider him, I have written to you briefly, exhorting and testifying that this is the true grace of God in which you stand. (1 Peter 5:12, NKJV)
Peter’s first epistle identifies and testifies of the true grace of God in which Christians stand. We take it as axiomatic, that since there is “the true grace of God,” there is also false grace that is not of God. False teachers, by their false gospels, turn people away from the true grace of Christ (Galatians 1:6-9). For instance, the doctrine of irresistible grace offers false grace, since it is evident the grace of God can indeed be resisted through unbelief (Acts 7:51). The doctrine of the perseverance of the saints (the impossibility of apostasy) offers false grace, since Scripture says Christians can fall from grace (Galatians 5:4). The doctrine of unity in moral and doctrinal diversity (ecumenism) offers false grace, by allowing one to continue in his sin, while assuring him of grace despite his sins (Romans 6:1-2; 2 John 9-11). On the other hand, the true grace of God provides salvation to all people through the gospel (Titus 2:11-12). It teaches us that, “denying ungodliness and worldly lusts, we should live soberly, righteously, and godly in the present age.” The “word of His grace” has power to save (Acts 20:32). But, only when we access God’s grace through an obedient faith in Christ (read Romans 5:1-2; 6:17-18).
