Paragraph 2

God alone is Lord of the conscience,12 and has left it free from the doctrines and commandments of men which are in any thing contrary to his word, or not contained in it.13 So that to believe such doctrines, or obey such commands out of conscience, is to betray true liberty of conscience;14 and the requiring of an implicit faith, an absolute and blind obedience, is to destroy liberty of conscience and reason also.15

Paragraph 3

They who upon pretence of Christian liberty do practice any sin, or cherish any sinful lust, as they do thereby pervert the main design of the grace of the gospel to their own destruction,16 so they wholly destroy the end of Christian liberty, which is, that being delivered out of the hands of all our enemies, we might serve the Lord without fear, in holiness and righteousness before Him, all the days of our lives.17
