The heart of your question touches on the views of salvation, unity, and diversity within the Christian faith. It’s important to remember, “For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.” (John 3:16) This verse underscores the Christian belief in salvation through faith in Jesus Christ.

The New Testament speaks to unity among believers and the importance of love. For example, Ephesians 4:4-6 says, “There is one body and one Spirit—just as you were called to the one hope that belongs to your call— one Lord, one faith, one baptism, one God and Father of all, who is over all and through all and in all.” This passage emphasizes the unity that exists within the diversity of the Christian faith.

It’s also important to reflect on the words of Jesus in John 13:34-35, “A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another. By this all people will know that you are my disciples, if you have love for one another.” This commandment to love underscores the importance of compassion and understanding among Christians, regardless of denominational differences.

The question of salvation and who attains it is ultimately known by God alone. Romans 10:9 states, “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.” This suggests that faith in Jesus Christ is the key to salvation.

In navigating these questions, it’s essential to approach them with a spirit of love, understanding, and unity as taught in Scripture, recognizing that the mystery of God’s grace and mercy is boundless and extends beyond human divisions.
