Whenever any person is required to take or subscribe an oath and shall have conscientious scruples against taking the same, he shall be permitted, instead of such oath, to make a solemn affirmation, with uplifted right hand, in the following form, viz: you do solemnly, sincerely and truly declare and affirm, and close with: and this I do under the pains and penalties of perjury, which affirmation shall be equally valid as if such person had taken an oath in the usual form; and every person guilty of falsely, willfully or corruptly declaring as aforesaid, shall be liable to punishment for the same as for perjury.
