Chapter 2 in Ephesians is full of powerful doctrine. There is more than I can cover without turning this post into a casserole of Utah proportions (this is simply a reference to the popularity of casseroles in Utah – they are usually simple to prepare and can feed a lot of people, so they are useful for church functions).
Paul (we assume Paul wrote this epistle) talks about Christ’s role as Reconciler. He redeems us from our fallen state: “But now in Christ Jesus ye who sometimes were far off were made nigh by the blood of Christ.” (Eph. 2:13). When we are fallen or when we are not part of Christ’s covenant people (i.e., Gentiles), we are strangers. We are separated from the flock. Christ’s blood brings us near, it removes the title of stranger, adding the title of fellow citizen with the saints: “Now therefor ye are no more strangers and foreigners, but fellow citizens with the saints, and of the household of God.” (Eph. 2:19).
That is an important thing to keep in mind – that we (members of the Church) are of the household of God. Who are household members? They are family (this is one reason why in The Church of Jesus Christ of Latter-day Saints we call each other “brother” and “sister” {we are also all spirit brothers and sisters}). So we, through the blood of Christ, become sons and daughters of God. We all are spiritually but through sin – none of us is perfect – we suffer spiritual death. Christ’s Atonement gives us life as we repent, which is how we accept His redemption. Repentance is more than just a verbal and spiritual acknowledgment, it involves real contrition; it also involves ordinances – baptism and confirmation and the sacrament. Through Christ’s Atonement we can be adopted back into God’s family. What does it mean to be a son or daughter? It means that we have the potential of the parent.
Now we get to another interesting verse. Those who are saved by Christ, who are now fellow citizens with the saints (meaning those who have joined Christ’s church) “are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone; In whom all the building fitly framed together growth unto an holy temple in the Lord.” (Eph. 2:20-21). So those in Christ’s church (again, this is anyone who is redeemed – which is a process, it’s not a one-time event – by the blood of Christ) must be built upon a foundation of the apostles and prophets. Some might believe that Christ gave us the original apostles and they were enough, however, Judas Iscariot was replaced and Saul/Paul was later called as an apostle so clearly there was a pattern established to have new apostles called when needed. Paul also stated: “And he [Christ] gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers; For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ: Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ.” (Eph 4:11-13). These are things that have not happened yet – a unity of the faith; knowledge of the Son of God unto a perfect man. We still have a lot of work to do until we reach those goals. What this means is that apostles, prophets, evangelists (called Patriarchs in the LDS Church), pastors (we in the LDS Church use the term “Bishop” but the role is the same), and teachers all should be part of Christ’s church. So our foundation as members of Christ’s household is upon prophets and apostles. We need them to guide us and to help perfect the saints and perform the work of the ministry. They are our sure foundation with Christ as the Chief Cornerstone. Christ is the chief prophet and apostle; He is more than prophet and apostle, of course, but those callings are His to bestow on others.
Thus, Christ’s church has to have prophets and apostles. His church is the “building fitly framed” in which the saints dwell (in this case Christ’s church is not restricted to an earthly institution, it includes His organization in Heaven. So when we as a church – when we as members of the church – are truly saved by Christ’s blood, we can become sanctified as a holy temple in the Lord. This sanctification is the process that truly lifts us to God as His sons and daughters. This process is only possible through Christ’s redeeming blood.
