most dont even post that ,to find what the Methodist believe ,I go outside and yes they teach what Wesley taught .Yes! That is exactly what he should do. It's known as a non-denominational church, and there are many of them.
The pastor will teach what HE believes to be correct.
If this person wants to teach in, for instance, as Assembly of God denominational church - then he must teach what
that particular denomination states in their Statement of Faith.
sinless perfection ,with your practice ,you can by faith be so santucifued that your love is flawless and also loose it .
the Wesleyan definiton is that you can become so loving that your spirit would plan on sinning and mature in love but you will still commit acts of sin by omission
the oldest church in America ,being the Presbyterian after the Anglican ,has splits on silly issues
just from the same Westminster confession .
there's the pca,pcua,eco,arp the oldest being the arp.
that's over baptism of children which the arp does,the full water or sprinkling argument and other issues that are hair splitting .
I grew up in a controlled and limited ,no,the elders don't actually have the ability to teach from,their own reading ,here's our doctrine from the hq,.rather then have as my church does in hymnals and quotes it .most churches as you say indeed dont.
in your case the church would teach its version of the Christian faith .while that can happen in my church the pastor believes in the 5 points ,he would rather you know the bible and why he is wrong or correct based your reading it!
