As a Christian, I think there’s a little thing in Eph:4:2 that would kind of get in the way of mocking another person’s faith.
Ephesians 4 is about Unity and maturity within the body of Christ. Is is about how Christians are to treat one another. 2 reads, Be completely humble and gentle, be patient, bearing with one another in love. 3. Make every effort to keep the unity of the Spirit through the bond of peace. Go on to verse 4. There is one body and one spirit, Just as you were called to one hope when you were called; one Lord, one faith, one baptism; one God and Father of all........ There verses do no enjoin one to accept nor to celebrate other gods.
Do you think Paul is addressing everyone or Christians when he says we should humbly bear with each other? Are you saying Muslims share in the unity of the Spirit? I think they are due love as fellow human beings, deluded as they may be, but I don’t think Paul was speaking to everyone, believers and unbelievers, when he admonished the Christians in Ephesus to bear with each other.
I’ll say forthrightly that Islam is an abomination. What better way for Satan to pervert Christianity than to have one of his minions synthesize a new religion, Islam, out of Christianity and Judaism? Muslims think Christ was a nice guy, maybe even a prophet, but they deny He was the Son of God. What does scripture say about that?
