Your sin is no worse than mine was when I first heard the gospel. I was guilty of grave sexual sin before I came into the Church. I am not any better than you and I am still a sinner, but the difference is that I recognized the grave sin I was in and repented of it. What I say next is not condemnation. But, according the the Scripture I must speak truth to my brothers and sisters in Christ and I am called to correct you. If I did not, it would be a sin on me (Lv 19:17). Even though it’s popular to call us “haters” when we try to correct, it is really an act of love to correct. So I speak the truth of the Scripture as an act of love, not condemnation.
The world will tell you that homosexual acts are not a sin, but the Scriptures repeatedly attest to the opposite. Do you believe in the truth of the Scripture? Jesus’ first words of His public ministry were “This is the time of fulfillment. The kingdom of God is at hand. Repent, and believe in the gospel” Mk 1:15. You have to understand what sin is in order to repent from it and that is where “the world” has gone terribly astray. The “world” has exchanged the truth about God for a lie and worshiped and served the creature rather than the Creator (cf Rm1:25). Woe to those who call evil good, and good evil; who put darkness for light, and light for darkness.(Is 5:20) Those (non-Catholic) Christian communities, that ignore the Scriptural truth on grave sin, repentance, and the life to which we Christians are called are not doing sinners any favors. Please consider prayerfully reading the Scriptures, not only the ones that I’ve included, but the Bible in its fullness. Ask the Lord to help you see where the sin is in your life and help you to repent. Jesus died for our sins but He only gives the promise of eternal life to those sheep who hear His voice and follow (cf John 10:28).
Many people boast of the freedom they have in Jesus not to be “rule bound” as the Jews were under the law. But if you use your freedom wrongly to sin, you will become enslaved to sin, and then where has your freedom gone?
