The following can be found on page 239 of (Commonwealth of Massachusetts) the Manual for the General Court 1997-1998:
Under the Constitution and Laws of the Commonwealth and of the United States every person chosen or appointed to any office, civil or military, under the government of this Commonwealth, before he enters on the duties of his office, is required to take and subscribe the following oath or affirmation:-
I,_______________________, do solemnly swear that I will bear true faith and allegiance to the Commonwealth of Massachusetts and will support the Constitution thereof. So help me, God.
I,_______________________, do solemnly swear and affirm that I will faithfully and impartially discharge and perform all the duties incumbent on me as ___________, according to the best of my abilities and understanding, agreeably, tothe rules and regulations of the constitution, and the laws of this Commonwealth - So help me God.
I,_______________________, do solemnly swear that I will support the Constitution of the United States.
Many legislators who swear to support the Constitution of the United States repeatedly vote for further infringement upon the Second Amendment rights of law-abiding citizens.
If you find a conflict between your legislator's sworn oath and his/her actions, let them know (always be polite but firm) Massachusetts Government Home Page at http://www.magnet.state.ma.us/toolbar.htm
