Peter 2:24 - “He Himself bore our sins in His body on the tree, so that we might die to sins and live for righteousness.”
Psalm 8:3-4 - “When I consider Your heavens, the work of Your fingers, the moon and the stars, which You have set in place, what is man that You are mindful of him, the son of man that You care for him?”
Ephesians 2:1,4-5 - “As for you, you were dead in your transgressions and sins… But because of His great love for us, God, who is rich in mercy, made us alive with Christ even when we were dead in transgressions — it is by grace you have been saved.”
2 Timothy 4:8 - “Now there is in store for me the crown of righteousness, which the Lord, the righteous Judge, will award to me on that day — and not only to me, but also to all who have longed for His appearing.”
1 John 5:13 - “I write these things to you who believe in the name of the Son of God so that you may know that you have eternal life.”
These are good verses but the NT ones are all addressed to Christians who are already baptised and received into the Catholic Church. Baptism removes the stain of sin so they are in fact on the narrow pathway to salvation. All of these who died in grace attained the salvation that was promised.
To backsliders and those not yet baptised into the Church the apostle warns us:
*
Rev 2:5 Remember therefore from where you have fallen;
repent, and do the works you did at first. If not, I will come to you and remove your lampstand from its place, unless you repent.
Rev 2:16 'Therefore repent; or else I am coming to you quickly, and I will make war against them with the sword of My mouth.
Acts 2:38 Peter replied, "Repent and be baptized, every one of you, in the name
of Jesus Christ for the forgiveness of your sins.
Luke 13:5 I tell you, no! But unless you repent, you too will all perish.
John 20:23 - Jesus says, “If you forgive the sins of any, they are forgiven. If you retain the sins of any, they are retained.” In order for the apostles to exercise this gift of forgiving sins, the penitents must orally confess their sins to them because the apostles are not mind readers. The text makes this very clear.
Cor. 5:18 - the ministry of reconciliation was given to the ambassadors of the Church. This ministry of reconciliation refers to the sacrament of reconciliation, also called the sacrament of confession or penance.
Acts 19:18 - many came to orally confess sins and divulge their sinful practices. Oral confession was the practice of the early Church just as it is today.
Matt. 3:6; Mark 1:5 - again, this shows people confessing their sins before others as an historical practice (here to John the Baptist).
1 Tim. 6:12 - this verse also refers to the historical practice of confessing both faith and sins in the presence of many witnesses.
1 John 1:9 - if we confess are sins, God is faithful to us and forgives us and cleanse us. But we must confess our sins to one another.
Don’t make the mistake of thinking Repentance is a one time event. We are called to repent every day of our life so that we can strive to be perfect as commanded.
Matt 5:48 Therefore you are to be perfect, as your heavenly Father is perfect.
James
