Further modifications in the exemption laws, made in 1770, were so slight, leaving as they did the certificate principle practically untouched,[70] that Baptist opposition was aroused even more deeply and the determination struck deeper root to push the battle for religious freedom to a decision. The times also were propitious. The near approach of the Revolutionary struggle focused attention upon the subject of tyranny and caused acts of oppression, whether civil or ecclesiastical in character, to stand out in a new relief before the eye of the public. That dissenters were quick to see the bearing of political events will appear from the following pithy comments in the address which the Committee of Grievances[71] drew up late in 1774 and presented to the Provincial Congress of Massachusetts: It seems that the two main rights which all America are contending for at this time, are,—Not to be taxed where they are not represented, and—To have their causes tried by unbiased judges. And the Baptist churches in this province as heartily unite with their countrymen in this cause, as any denomination in the land; and are as ready to exert all their abilities to defend it. Yet only because they have thought it to be their duty to claim an equal title to these rights with their neighbors, they have repeatedly been accused of evil attempts against the general welfare of the colony; therefore, we have thought it expedient to lay a brief statement of the case before this assembly.... Great complaints have been made about a tax which the British parliament laid upon paper; but you require a paper tax of us annually. That which has made the greatest noise, is the tax of three pence a pound upon tea; but your law of last June laid a tax of the same sum every year upon the Baptists in each parish, as they would expect to defend themselves against a greater one.... All America is alarmed at the tea tax; though, if they please, they can avoid it by not buying tea; but we have no such liberty. We must either pay the little tax, or else your people appear even in this time of extremity determined to lay the great one upon us. But these lines are to let you know, that we are determined not to pay either of them; not only upon your principle of not being taxed where we are not represented, but also because we dare not render homage to any earthly power, which I and many of my brethren are fully convinced belongs only to God. We can not give the certificates you require, without implicitly allowing to men that authority which we believe in our conscience belongs only to God. Here, therefore, we claim charter rights, liberty of conscience.[72]
