Interesting that Dr. Featley's evidence should be so revered. His testimony is that there were "Anabaptists" in the 1620s, which seems to me be rather unremarkable.
Still, before one establishes Featley as an expert upon all things Baptistic, listen to Samuel Richardson, a Particular Baptist pastor and signer of the First London Confession, who responds to The Dippers Dipt:
But the Doctor charges us in his book, with many things that we hold:
That no malefactor ought to be put to death,
That it is lawful to have more wives then one at once,
That a man may put away his wife if she differ from him in point or religion,
That we are to go naked, and not be ashamed,
That we hold it lawful to slay wicked Magistrates,
That no Christian may go to law, but right himself by violent means,
That wicked men have no properiety in their goods, but all things ought to be hold in common,
That we maintain pretended Revelations,
That Christ took not flesh of the virgin Mary,
That there is no original sin,
That men have free will in spiritual actions,
That election is for foreseen faith and repentance,
That God gives all men sufficient grace to be saved,
That a man hath free will of himself to accept or refuse grace, That Christ died indifferently alike for all,
That a true believer may fall away from grace totally and finally,
And that we hold Libertinism & Familism, and such like stuff which we utterly abhore and detest; and if God permit, we shall in the next impression of the Confession of our Faith, more fully declare jointly what we believe, and therefore I will not answer his exceptions, which he makes at some of the Articles, but leave it to them to answer for themselves, which will be before long, if God permits.
But I am sure, all this poison (which he charges upon us) is drawn out of the impure fountain of divers Heretics, in which he labors to drown us in; and I wonder how his conscience would permit him to heave so many untruths into the Press; but (as Christ said, John 16:2, and) he was encouraged by Sleiden, Grabriel, Abres, Alsterdus, and others, Oh, I think I hear the press grone, if not sweat under the burden of so many heavy charges; and sure his grones will be much greater when God opens his eyes, and shows him what he hath done, which the Lord in mercy do, if it be His will. I hope I may say as Christ did, Father forigve him, for he knows not what he has done, (Matt. 5:44, 11,12).
