And exactly which of the 50,000 denominations, sects, schisms, and personal opinions etc. might that be?
What I have noted is that people tend to attend the churches with doctrines that concur with their personal opinions. And if the Pastor offends them with some preaching, they go down the street to another church that is more to their liking. Rather than "Charismatic", they are more "cruise-amatic."
Most have no idea from where their church's doctrine comes and have never heard of the early church fathers.
One chap, when told about Poly carp asked, "Did Polycarp speak in tongues?" So much for being able to discern which church has the "correct doctrine."
God's word does not allow for "freedom of thought and conscience."
Deviation from God's truth is described by the word, "heresy."
Examples of attempts to exercise "freedom of thought" include, Arianism, Nestorianism, Modalism, Gnosticism, Manichaeism, Montanism, Docetism, and a host of other heresies. The one benefit of the doctrines of these "free thinkers" was that it forced the church to precisely define it's doctrine over the first 8 centuries. The "reformation" introduced a resurgence of the invention of novel doctrines by men exercising their "freedom of thought and conscience" which has brought us to the very sad fracturing of the body of Christ into tens of thousands of squabbling fragments we see today and which provide evidence be which the pagan concludes that God could not possibly have created such confusion. They are correct.
Freedom of conscience is described at 1Ti 4:1-2
But the Spirit explicitly says that in later times some will fall away from the faith, paying attention to deceitful spirits and doctrines of demons, by means of the hypocrisy of liars seared in their own conscience as with a branding iron,
The idea that the average man with what passes for an education today is capable of precise exegesis, and by his education being able to determine which church has the "correct doctrine" is akin to the same average man reading a book on medicine and then proceeding to perform brain surgery.
But what do I know????
iakov the fool
PS: Notice I did not make the claim that the age old Roman, Orthodox, Coptic, Syrian, etc. churches are perfect.
