King's Chapel, with its ancient burying-ground, is one of the most famous churches in Boston, having been the chapel of the royal governor, officers of the army and navy, and other official representatives of the "principalities and powers" of the mother country. Massive, almost sombre, in its exterior, and quaint and picturesque within, the old church stands, with few changes, as erected in 1749, with its old-fashioned pulpit and sounding-board, prim, straight pillars, and antique high-backed pews which recall the remark of the little girl, that when she went to church she "went into a cupboard and climbed up on the shelf." Its burying-ground is believed to be the oldest in the city. Christ Church, built in 1723, is the oldest church edifice in the city. Its age-mellowed chime of bells was the first ever brought into this country, and the first American Sunday-school was established there in 1816. To-day its tall steeple, which on the eve of Lexington's conflict bore the signal lanterns of Paul Revere, is the most conspicuous object in the North End, where the old-time aristocrats who worshipped in Christ Church have given place to a poverty-stricken foreign population to whom the church is little and its traditions less. Churches which well deserve more extended mention, could space permit, are the beautiful Gothic Cathedral of the Holy Cross, with its fine organ and splendid high-altar of onyx and marble; Tremont Temple, whose hall is the largest in Boston; and the South Congregational Church, presided over by Rev. Edward Everett Hale, author of "The Man without a Country" and other world-famous literary productions, and originator of the equally famous "Ten Times One" clubs. Boston's religious history is most interesting, although almost kaleidoscopic in its changes. From being the stronghold of Puritan orthodoxy it has become the headquarters of liberal Unitarianism. King's Chapel is a curious instance; originally an Episcopal church and congregation, it became Unitarian in 1787, retaining the Episcopal liturgy with necessary changes, and now doctrines are preached over the tombs of the dead dignitaries interred beneath the church floor, diametrically opposed to those in which they lived, died and were buried. Though all denominations of course flourish within her walls, Boston is still strongly Congregational in her leanings.
