“A false Church with No significant truths”
The Fundamental Difference between Protestants and Roman Catholics is this: Rome does not see salvation from start to finish as the work of the triune God alone. Thus, justification before God (salvation) is not through faith alone by God’s grace alone, but, as Rome teaches, salvation comes by faith + the meritorious works that a man must do (including unquestionable devotion to Rome and “worship” to Mary (in the form of “hyperdulia”)
Paul’s main thesis in Romans: God’s method of justification does not change. He offeres Abraham (pre-law) and David (under the law) as his chief examples: “God credits [logizetai] righteousness chōris ergōn (apart from works, Rom. 4:6).
Although Catholics, in their mind, do not give Mary latria (Gk. latreia) “worship” reserved to God alone, by giving her so-called dulia (Gk. douleia), that is, hyperdulia (hyper-service/enslavement), they functionally give her religious “worship,” which is reserved for God alone and prohibited by God, who commanded His people: “You shall not worship them or serve [Heb. avad] them; for I the LORD your God, am a jealous God” (Exod. 20:5). In a religious context, Scripture makes no distinction between latreia and douleia – as Paul shows: “When you did not know God, you were slaves [douleuō] to those which by nature are no gods” (Gal. 4:8). Along with a functional “worship” to Mary, Rome asserts of her:
There can be no doubt . . . Mary was made mediatress of our salvation. . . . St. Bonaventure says that Mary is called “the gate of heaven because no one can enter that kingdom without passing through her . . . . Go to Mary, for she will intercede for thee with the Son. . . .” (St. Alphonsus Ligouri, The Glories of Mary, 160, 201–see below article on the Catholicism and the worship of Mary).
Rome denies that the work of Jesus Christ completely sufficient for salvation. That faith plus meritorious works must be employed for salvation (as Rome teaches) is, according to the Apostle Paul, Christological heresy (cf. Gal. 1:6-8)–it rejects the work of Christ and hence rejects the Person of the Son, Jesus Christ.
The Christ of Rome is Not a Diligent Savior; As Rome believes, He cannot keep baptized Christians In His Hand – they keep falling out – There is NO perseverance or Definite Atonement For anyone.
Rome’s doctrine of Purgatory, for example, is that when a Christian dies without un-forgiven mortal sins, but who retain either un-forgiven daily sins (viz. venial sins) or “temporal punishment” due for sins are “purged” before entering heaven, so as to be made perfect. In other words, they must suffer for these sins in a place of torment (not hell, though) to be, so to speak, “scrubbed up” (viz. purified) before they can dwell with God in heaven.
Thus, the work of Christ, according to Rome, is not completely sufficient to atone and *justify* a sinner–for one must suffer for his or her own atonement in order to become righteous (just) before God.
Though Scripture testifies in passages such as Hebrews 10:10-14
10:10: By his will we have been made holy through the offering of the body of Jesus Christ once for all.
10:11: And every priest stands day after day serving and offering the same sacrifices again and again – sacrifices that can never take away sins.
10:12: But when this priest had offered one sacrifice for sins for all time, he sat down at the right hand of God . . .
10:14: For by one offering he has perfected for all time those who are made holy.
Therefore, since we have been declared righteous by faith, we have peace with God through our Lord Jesus Christ, 5:2 through whom we have also obtained access by faith into this grace in which we stand, and we rejoice in the hope of God’s glory (NET; See Justification through Faith Alone).
As with Mormons and Jehovah’s Witnesses, we must see Catholics as men and women in need of evangelism. One cannot biblically claim to be truly Christian and reject Christ as the sole means of salvation, justification through faith alone, and engage in creaturely worship.
