How would you define a true New Testament Church? What are the basic doctrines it must hold in order to qualify? What doctrines which you consider false would disqualify a congregation as a NT church? Which beliefs are not essential and would not disqualify? For instance, can Arminian churches qualify as NT churches? Can sprinkling and pouring churches qualify? If a church does not teach a substitutionary atonement or imputed righteousness, is it disqualified? What about a congregation which admits gay and lesbians to membership, and/or ordains gay or lesbian clergy? Further, if you determine what a NT church should believe, would you admit to membership someone who comes from a church that does not believe those things?
