Is God sovereign?
Did He found a church?
Did He promise that the gates of Hell would not prevail against His church?
Did He promise the Holy Ghost to guide His church in all things?
Would He allow His sheep to be without a shepherd for 1500 years? If He would, why not 1800 until He sent Joseph Smith?
Were His sovereign powers sufficient to prevent His entire church from "wandering off into heresy"?
***Is God sovereign?***
Yup, though Catholics and reformed folk differ on what that means.
***Did He found a church?***
Of Course He did, and it ain’t in Rome. It is Jesus Christ.
***Did He promise that the gates of Hell would not prevail against His church?**
Yup. And in spite of the heresy found in Rome His church is thriving among Baptists, PCA, URCNA, LCMS and countless other Bible preaching churches.
***Did He promise the Holy Ghost to guide His church in all things?***
Yup. And a certain church HQ’ed in Rome has derailed.
***Would He allow His sheep to be without a shepherd for 1500 years? If He would, why not 1800 until He sent Joseph Smith?***
He didn’t, he gave us the Holy Spirit.
***Were His sovereign powers sufficient to prevent His entire church from “wandering off into heresy”?***
Yes, but we also see in Revelation that he has/will remove the golden lampstand from churches that stray. So evidently he allows churches (ie Rome) to leave the fold for reasons we are not privy too.
