Because the Catholic church has added so much to the Gospel and the life of the Christian with regards to salvation, I thought it would be helpful to include an outline from a sermon I gave on this very topic. Just about everything on the outline below argues against the Catholic doctrines.

Salvation Through Christ Alone

My salvation is not based on my performance.
Christ alone is the only one able to complete the work of salvation (Eph 2:8-9)
For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast.
1. Salvation through faith in Christ (Rom 5:1)
  Therefore, since we have been justified by faith, we have peace with God through our Lord Jesus Christ.
  1. His perfect life (1 Peter 2:22)
    He committed no sin, neither was deceit found in his mouth.
  2. His sacrificial death (Mark 10:45)
    For even the Son of Man came not to be served but to serve, and to give his life as a ransom for many.
  3. His victorious resurrection (1 Cor 15:14)
    And if Christ has not been raised, then our preaching is in vain and your faith is in vain.
2. Not by our works… (John 6:27-29)
  Do not work for the food that perishes, but for the food that endures to eternal life, which the Son of Man will give to you. For on him God the Father has set his seal.” Then they said to him, “What must we do, to be doing the works of God?” Jesus answered them, “This is the work of God, that you believe in him whom he has sent.”
  1. None of us can be good enough (Rom 3:10)
    as it is written: “None is righteous, no, not one;
  2. No one can prescribe enough good works (Gal 2:16)
    Yet we know that a person is not justified by works of the law but through faith in Jesus Christ, so we also have believed in Christ Jesus, in order to be justified by faith in Christ and not by works of the law, because by works of the law no one will be justified.
  3. Only Jesus could perform the work of salvation (Gal 3:1)
    O foolish Galatians! Who has bewitched you? It was before your eyes that Jesus Christ was publicly portrayed as crucified.
3. Even our faith comes from him (Eph 2:8-9)
  For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast.
  1. Our faith is a gift (Rom 10:17)
    So faith comes from hearing, and hearing through the word of Christ.
  2. God draws us (John 6:44)
    No one can come to me unless the Father who sent me draws him. And I will raise him up on the last day.
My salvation is not provided by other people.
Christ alone is the only mediator between God and man (1 Tim 2:5-6)
For there is one God, and there is one mediator between God and men, the man Christ Jesus, who gave himself as a ransom for all, which is the testimony given at the proper time.
1. We don’t need a priest (1 Tim 2:5-6)
  For there is one God, and there is one mediator between God and men, the man Christ Jesus, who gave himself as a ransom for all, which is the testimony given at the proper time.
  1. We have been made a royal priesthood (1 Pet 2:9)
    But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light.
  2. Jesus is the great high priest (Heb 4:14)
    Since then we have a great high priest who has passed through the heavens, Jesus, the Son of God, let us hold fast our confession.
  3. Jesus offered the only priestly sacrifice we needed (Heb 7:27)
    He has no need, like those high priests, to offer sacrifices daily, first for his own sins and then for those of the people, since he did this once for all when he offered up himself.
2. We don’t need Mary (John 14:13)
  Whatever you ask in my name, this I will do, that the Father may be glorified in the Son.
  1. Mary was used by God but still fallen (Rom 3:23)
    For all have sinned and fall short of the glory of God.
  2. We can’t worship or pray to anyone but God (Revelation 19:10)
    Then I fell down at his feet to worship him, but he said to me, “You must not do that! I am a fellow servant with you and your brothers who hold to the testimony of Jesus. Worship God.” For the testimony of Jesus is the spirit of prophecy.
3. Only Jesus makes a relationship with God possible (Eph 2:18)
  For through him we both have access in one Spirit to the Father.
  1. The veil was torn (Matt 27:51)
    And behold, the curtain of the temple was torn in two, from top to bottom. And the earth shook, and the rocks were split.
  2. He gives us confidence to approach God (Heb 10:19-20)
    Therefore, brothers, since we have confidence to enter the holy places by the blood of Jesus, by the new and living way that he opened for us through the curtain, that is, through his flesh.
My salvation is not found along other paths.
Christ alone is the only way to heaven (Jn 14:6)
Jesus said to him, “I am the way, and the truth, and the life. No one comes to the Father except through me.
1. There is nothing we can do to earn our salvation (Acts 13:39)
  And by him everyone who believes is freed from everything from which you could not be freed by the law of Moses.
  1. No one does good (Psalm 14:3)
    They have all turned aside; together they have become corrupt;
    there is none who does good,
    not even one.
  2. Our thoughts are only evil (Rom 5:12)
    Therefore, just as sin came into the world through one man, and death through sin, and so death spread to all men because all sinned.
2. There’s no other path to salvation (Matt 7:13-14)
  Enter by the narrow gate. For the gate is wide and the way is easy that leads to destruction, and those who enter by it are many. For the gate is narrow and the way is hard that leads to life, and those who find it are few.
  1. No other religion (Isaiah 44:6)
    Thus says the Lord, the King of Israel
    and his Redeemer, the Lord of hosts:
    “I am the first and I am the last;
    besides me there is no god.
  2. No other philosophy (Col 2:8)
    See to it that no one takes you captive by philosophy and empty deceit, according to human tradition, according to the elemental spirits of the world, and not according to Christ.
  3. No other lifestyle (Isaiah 53:6)
    All we like sheep have gone astray;
    we have turned—every one—to his own way;
    and the Lord has laid on him
    the iniquity of us all.
3. There’s no other person sent to save us (John 3:16-17)
  For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him.
  1. There is no other name by which people are saved (Acts 4:12)
    And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved.
  2. No other prophet (1 John 4:1)
    Beloved, do not believe every spirit, but test the spirits to see whether they are from God, for many false prophets have gone out into the world.
  3. No other lord (Rom 10:9)
    Because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved.
