Caspar Olevianus, A Firm Foundation, Question 132 (translated by Lyle D. Bierma [more info])
Q. What do you believe when you confess, "I believe a holy catholic church"?
A. I believe that the Son of God, out of the entire human race, which is mired in sin and eternal death, gathers unto Himself from Adam to the end of the world a people chosen for eternal life by grace and not by merit, whom He through the preaching of the Word and power of the Holy Spirit here in this life regenerates from eternal death through faith in Him. As He Himself testifies in Jn 5.25: "Most assuredly, I say to you, the hour is coming and now is, when the dead will hear the voice of the Son of God, and those who hear will live." See also Eph 2.
He also makes an eternal covenant with and betrothes Himself to this people as if they were a bride (Hos 2, Isa 54), that they might be His body in true faith through the testimony of the Holy gospel and covenant sign of Holy Baptism. He promises his church that he will remember her sins no more (Jer 31.34) because he has given Himself for her, will sanctify her daily, until He finally presents her to Himself holy, pure, and spotless in body and soul, and she lives and reigns with Him forever. All of this He does out of grace, because He loved her and gave Himself for her (Eph 5.25).
I believe that I am and always will be a member of this church or people of God (Jn 10.28-29), since I believe in Christ, have been baptized into His name, and trust the promise, "Whoever believes and is baptized will be saved" (Mk 16.16). I believe and am baptized; therefore I shall be saved. That is the only way, for Christ promised it.
[Question & answer Copyright 1995 Lyle D. Bierma]
First, many protestant-types get all afluster when they read this article of the creed due simply to the word "catholic". Even though they intellectually understand that this article does not refer specifically to the Roman Catholic Church, it's a stumbling block. More important is to notice Olevianus' phrasing "I believe a holy catholic church" instead of what some folks must actually think/read (and what is most definitely not meant), "I believe in the Holy Catholic church". See the difference? The creed has the indefinite article "a", not the definite article "the". Olevianus discusses this in question 133, which I won't reproduce here.
Some folks like to replace "catholic" with words like "universal" or even "Christian". But the word in the received Greek and Latin forms of the creed is obvious:
Latin: sanctam ecclesiam catholicam
Greek: ἀγίαν καθολικὴν ἐκκλησίαν
This word was used to describe the church "at large" long before it was used to describe a particular (albeit large) body with a particular doctrinal stance. So I like to keep it in the creed when I recite it, even though it may confuse some. But I'm more of a traditionalist and a bit of a stickler when it comes to using the proper word in the proper situation despite the perception of the word's meaning by the masses.
Second (though primarily) this is an awesome description of the church. Olevianus says that the church (that is, Christians in the world) are provided for by God, who has gathered His church together throughout all time. He provides for the primary need of His chosen through the provision of salvation in Jesus Christ, our Lord, Savior and Mediator. He provides not only the faith for belief; but also the daily needs, encouragement and comfort for his chosen through the provision of the Holy Spirit. Amazingly, Jesus Christ is bound to the church in a manner similar to the way a husband is bound to his wife. He ministers to us, and we follow His leadership. All in all, it reminds me of Titus 2.11-15:
11 For the grace of God has appeared, bringing salvation for all people, 12 training us to renounce ungodliness and worldly passions, and to live self-controlled, upright, and godly lives in the present age, 13 waiting for our blessed hope, the appearing of the glory of our great God and Savior Jesus Christ, 14 who gave himself for us to redeem us from all lawlessness and to purify for himself a people for his own possession who are zealous for good works. (ESV)
Even though Olevianus hasn't quoted this passage, this is basically what he is saying. Through the sacrifice and resurrection of Jesus Christ, God has acted to provide salvation for His people. This salvation and the grace upon which it is founded is transforming. It brings His people closer to Him in prayer, worship and obedience. It also brings people closer to Him through renouncement and repentance of vices and vanities. This transformed (and transforming) people eagerly await the triumphant return of Jesus Christ, our redeemer. This expectant group -- those who by the grace of God and who through the work of the Holy Spirit have claimed Jesus Christ as their Lord, Savior and Redeemer -- lives according to His will. Through the continual work of the Holy Spirit this group is in the process of being sanctified, being brought closer to Him and being cultivated to live lives of worship in praise and thankfulness to the One who has provided salvation.
This is the "holy catholic church". When we recite the creed, we are not simply professing belief that a body of some sort exists, we are professing that a specific body exists for a specific purpose, and that God acts to gather and assemble this group, as He has promised, and that His wishes and desires for this group will come to pass.
