The Religion and Seafarers' Welfare units are meant to help one think about seafarers and seafarers' welfare in spiritual terms. Like many seafarers' welfare organizations, it has a Christian perspective, but it is not meant to be exclusive: the point is to consider the relationship among seafarers' welfare, their religion, and ours, whatever it might be.
In thinking about seafarers' ministry, it is important to think not only about what makes the sea special and sacred, but all the other aspects of seafaring life: travel and isolation, commerce, and providing for family, e.g. This third unit, How Are Seafarers Sacred?, considers all these things from the perspective of religious ministry.
