There's nothing new under the sun!
Someone demands, "How am I to know which is the gospel?"
You may know it by searching the Scriptures.
"But one sect says this, and another sect says the reverse."
What have you to do with the sects? Read the Book of God for yourself.
"But some men do read it and arrive at one opinion, and some maintain the opposite, and thus they contradict themselves, and yet are equally right."
Who told you that? That is impossible. Men cannot be equally right when they contradict each other. There is a truth and there is a falsehood; if yes be true, no is false. It may be true that good men have held different opinions, but are you responsible for what they may have held, or are you to gather that because they were good personally, therefore everything they believed was true? No, but this Book is plain enough; it is no nose of wax that everybody may shape to what form he likes. There is something taught here plainly and positively, and if a man will but give his mind to it, by God's grace he may find it out.
