Not at all. The Scriptures are plain enough when it comes to practice.
Read 1st John 2:27
Following is a little note from the Pilgrim Fathers, whom you would probably disdain, though you benefit greatly from their insight and heritage.
It is great arrogance for any man or Church to think that he or they have so sounded the word of God to the bottom as to be able to set down precisely a Church's practices without error in substance or circumstance, and in such a way that no one thereafter may digress or differ from them with impunity.
Forgot to footnote “Of Plymouth Plantation” as the source of that quote.
