Answ. This cannot be truly answered without distinguishing, 1. Of the countries they go from. 2. Of the places they go to. 3. Of the quality of the persons that go. 4. Of the causes of their going.

I. Some countries that they go from may be as bad as those that they go to, or in a state of war, when it is better to be absent, or in a time of persecution, or at least of greater temptation than they are like to have abroad. And some are contrarily as a paradise in comparison of those they go to, for holiness and helps to heaven, and for peace and opportunities of serviceableness to God and the public good.

II. Some countries which they may go to, may have as good helps for their souls as at home, if not by those of the religion of the nation, yet by christians that live among them, or by the company which goeth with them; or at least there may be no great temptations to change their religion, or debauch them, either through the civility and moderation of those they live among, or through their sottish ignorance and viciousness, which will rather turn men's hearts against them. But some countries have so strong temptations to corrupt men's understandings through the subtlety of seducers, and some have such allurements to debauch men, and some such cruelties to tempt them to deny the truth, that it is hard among them to retain one's innocency.

III. Some that go abroad are understanding, settled christians, able to make good use of other men's errors, and sins, and ill examples or suggestions, and perhaps to do much good on others; but some are young, and raw, and unexperienced, whose heads are unfurnished of those evidences and reasons by which they should hold fast their own profession against the cunning reasonings of an adversary, and their hearts are unfurnished of that love to truth, and that serious resolution, which is necessary to their safety, and therefore are like to be corrupted.

IV. Some are sent by their princes as agents or ambassadors on employments necessary to the public good; and some are sent by societies on business necessary to the ends of the society; and some go in case of extreme poverty and necessity, having no other way of maintenance at home; and some go in obedience to their parents and masters that command it them; and some go to avoid the miseries of a war, or the danger of a sharp persecution at home, or the greater temptations of a debauched or seducing age, or some great temptations in their families. But some go for fancy, and some for mere covetousness, without need.

By these distinctions the case may be answered by men that are judicious and impartial. As,

I. Affirm. 1. It is lawful for ambassadors to go among infidels, that are sent by princes and states; because the public good must be secured.

2. It is lawful for the agents of lawful societies or trading companies to go (cæteris paribus, the persons being capable); because trade must be promoted, which tendeth to the common good of all countries.

3. It is not only lawful, but one of the best works in the world, for fit persons to go on a design to convert the poor infidels and heathens where they go. Therefore the preachers of the gospel should not be backward to take any opportunity, as chaplains to ambassadors, or to factories, &c. to put themselves in such a way.

4. It is lawful for a son or servant (whose bonds extend to such a service) to go in obedience to a superior's command; and God's special protection may be trusted in a way of obedience.
