Izzy, too quote John Calvin (and i'm not a calvinist)
"A dog barks when his master is attacked, i should be a coward if God's truth is attacked and i should not respond"
Yes i'm not always as soft in my speech as i should, i know that, but that doesn't make me a bad christian... 'cause you aren't perfect either, and i don't judge your unperfections as a measure to your faith.
I have much to grow in Christ, and will do so till the end of my life... I strive for spiritual perfection because i know i do not have it.
So excuse my speech if it sounded harsh to you...
yet back to the subject,
read the Galatians as i asked you
"...if we, or an angel from heaven, preach any other gospel to you than what we have preached to you, let him be accursed... again... let him be accursed." -- Galatians 1:8-9
that line alone covers Islam.
As long as Islam teached another gospel it isn't christian, and pretty much accursed. Jesus warned us about false prophets for a reason... and accepting them wasn't it.
By the way i know what my nickname is, but that doesn't mean i worship and ancient pagan God... if i had my name to Donald Duck, George Clooney or a Coocookclock would that mean that i worshipped that?
