Final answer:
Theodorus Frelinghuysen, a minister of the Dutch Reformed Church, revitalized the Christian college through an approach that emphasized Protestant revivalism and personal piety, which inspired the establishment of institutions like Brown University and Dartmouth College.
Step-by-step explanation:
The Dutch man who revitalized the Christian college was Theodorus Frelinghuysen, a minister of the Dutch Reformed Church. Frelinghuysen used an approach that inspired other ministers, which led to a revival of Protestantism. This effort included the founding of a seminary to train evangelical clergy and the establishment of colleges that would become Brown University and Dartmouth College. This movement was part of a broader wave of Protestant revivalism in the Middle Colonies, characterized by a focus on personal piety and inner spiritual transformation over external religious practices.
