"I think the reason there's so many different churches is that Satan has succeeded in stealing a bunch of folks away from the faith"
Maybe it is the reverse and people have escaped to the true faith. When people are set free there is pandemonium for a while "Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ". Unity is not uniformity.
So your position is that nobody lived in the "true faith" before the early 16th Century? And if this is the case, then why didn't everyone flee the Church in order to embrace a SINGLE "true faith"? The fact that Protestant groups have as many disagreements with each other as they do with the Church indicates that your suppositions are invalid.
I dunno.
There began 1 church.
At the time of the Great Schism it could be argued there were as many as 4-6. That was within 1000 years of Christ.
At which point the West has gone from 1 church into 20,000+.
To be sure Satan is leaping for joy at this.
He must laugh ecstatically when he sees churches professing to be the church Christ established but advocating women preaching in church, abortion to 'help the poor', blessing gay marriages, ordaining gay church leaders...
In 1250 Christians were crusading against other Christians. Murdering them, stealing from them, raping nuns.
By the Reformation Christians were murdering Christians for baptising children.
Today 'Christians' work hard to steal other professed Christians into churches that condone abortion, gay marriage, hay lifestyles, and every manner of sin which Christ spoke against.
I fail to see that as a sign that things are 'getting better'.
