The two priests of the first Maryland company began their work with characteristic earnestness and diligence. Finding no immediate access to the Indians, they gave the more constant attention to their own countrymen, both Catholic and Protestant, and were soon able to give thanks that by God's blessing on their labors almost all the Protestants of that year's arrival had been converted, besides many others. In 1640 the first-fruits of their mission work among the savages were gathered in; the chief of an Indian village on the Potomac nearly opposite Mount Vernon, and his wife and child, were baptized with solemn pomp, in which the governor and secretary of the colony took part.
The first start of the Maryland colony was of a sort to give promise of feuds and border strifes with the neighbor colony of Virginia, and the promise was abundantly fulfilled. The conflict over boundary questions came to bloody collisions by land and sea. It is needless to say that religious differences were at once drawn into the dispute. The vigorous proselytism of the Jesuit fathers, the only Christian ministers in the colony, under the patronage of the lord proprietor was of course reported to London by the Virginians; and in December, 1641, the House of Commons, then on the brink of open rupture with the king, presented a remonstrance to Charles at Hampton Court, complaining that he had permitted "another state, molded within this state, independent in government, contrary in interest and affection, secretly corrupting the ignorant or negligent professors of religion, and clearly uniting themselves against such." Lord Baltimore, perceiving that his property rights were coming into jeopardy, wrote to the too zealous priests, warning them that they were under English law and were not to expect from him "any more or other privileges, exemptions, or immunities for their lands, persons, or goods than is allowed by his Majesty or officers to like persons in England." He annulled the grants of land made to the missionaries by certain Indian chiefs, which they affected to hold as the property of their order, and confirmed for his colony the law of mortmain. In his not unreasonable anxiety for the tenure of his estate, he went further still; he had the Jesuits removed from the charge of the missions, to be replaced by seculars, and only receded from this severe measure when the Jesuit order acceded to his terms. The pious and venerable Father White records in his journal that "occasion of suffering has not been wanting from those from whom rather it was proper to expect aid and protection, who, too intent upon their own affairs, have not feared to violate the immunities of the church."[59:1] But the zeal of the Calverts for religious liberty and equality was manifested not only by curbing the Jesuits, but by encouraging their most strenuous opponents. It was in the year 1643, when the strength of Puritanism both in England and in New England was proved, that the Calverts made overtures, although in vain, to secure an immigration from Massachusetts. A few years later the opportunity occurred of strengthening their own colony with an accession of Puritans, and at the same time of weakening Virginia. The sturdy and prosperous Puritan colony on the Nansemond River were driven by the churlish behavior of Governor Berkeley to seek a more congenial residence, and were induced to settle on the Severn at a place which they called Providence, but which was destined, under the name of Annapolis, to become the capital of the future State. It was manifestly not merely a coincidence that Lord Baltimore appointed a Protestant governor, William Stone, and commended to the Maryland Assembly, in 1649, the enacting of "an Act concerning Religion," drawn upon the lines of the Ordinance of Toleration adopted by the Puritan House of Commons at the height of its authority, in 1647.[59:2] How potent was the influence of this transplanted Nansemond church is largely shown in the eventful civil history of the colony. When, in 1655, the lord proprietor's governor was so imprudent as to set an armed force in the field, under the colors of Lord Baltimore, in opposition to the parliamentary commissioners, it was the planters of the Severn who marched under the flag of the commonwealth of England, and put them to rout, and executed some of their leaders for treason. When at last articles of agreement were signed between the commissioners and Lord Baltimore, one of the conditions exacted from his lordship was a pledge that he would never consent to the repeal of the Act of Toleration adopted in 1649 under the influence of the Puritan colony and its pastor, Thomas Harrison.
