Upon this, Mr. Samuel Adams arose and said: "He would willingly join in prayer with any gentleman of piety and virtue, whatever might be his cloth, provided he was a friend of his country;" and he moved that the reverend Mr. Duché, of Philadelphia, who answered to that description, might be invited to officiate as chaplain. This was one step towards unanimity of feeling, Mr. Adams being a strong Congregationalist, and Mr. Duché an eminent Episcopalian clergyman. The motion was carried into effect; the invitation was given and accepted. In the course of the day, a rumor reached Philadelphia that Boston had been cannonaded by the British. It produced a strong sensation; and when Congress met on the following morning (7th), the effect was visible in every countenance. The delegates from the east were greeted with a warmer grasp of the hand by their associates from the south. The reverend Mr. Duché, according to invitation, appeared in his canonicals, attended by his clerk. The morning service of the Episcopal church was read with great solemnity, the clerk making the responses. The Psalter for the 7th day of the month includes the 35th Psalm, wherein David prays for protection against his enemies. "Plead my cause, O Lord, with them that strive with me: fight against them that fight against me. "Take hold of shield and buckler and stand up for my help. "Draw out, also, the spear, and stop the way of them that persecute me. Say unto my soul, I am thy salvation," &c., &c. The imploring words of this psalm, spoke the feelings of all hearts present; but especially of those from New England. John Adams writes in a letter to his wife: "You must remember this was the morning after we heard the horrible rumor of the cannonade of Boston. I never saw a greater effect upon an audience. It seemed as if heaven had ordained that psalm to be read on that morning. After this, Mr. Duché unexpectedly struck out into an extemporary prayer, which filled the bosom of every man present. Episcopalian as he is, Dr. Cooper himself never prayed with such fervor, such ardor, such earnestness and pathos, and in language so eloquent and sublime, for America, for the Congress, for the province of Massachusetts Bay, and especially the town of Boston. It has had an excellent effect upon every body here." [Footnote: John Adams' Correspondence and Diary.] It has been remarked that Washington was especially devout on this occasion--kneeling, while others stood up. In this, however, each, no doubt, observed the attitude in prayer to which he was accustomed. Washington knelt, being an Episcopalian.
