Bernard Arnzius Arsenius/Arentius/Arsentius was pastor of the Albany Lutheran church from 1671 to his death in 1691.

A native of Westphalia, Arnzius came to New York from North Holland where he had not collected a salary in over a year. After recovering from a long and arduous Atlantic crossing, Arnzius and his wife, Tryntie, came to Albany in May 1672. Before long, he settled into a pattern of summers in New York and winters in Albany. He also served a growing number of Lutherans living in the Hudson Valley between the colony's two major centers.

The life of Bernard Arnzius has not been assigned a CAP biography number. This profile is derived chiefly from church sources; Frederick L. Weis, The Colonial Clergy of the Middle Colonies (reprinted Baltimore, 1978), 4, and community-based resources.
