Matthias Martinius (Martini) (1572 – 30 December 1630) was a German Calvinist theologian and educator.
[2][3] The teaching at Bremen influenced in particular Johannes Cocceius, student under Martinius and Ludwig Crocius.
[5] Martinius and the Bremen academy played an important role in the later developments of covenant theology.
His views as Calvinist were considered moderate, and anticipated hypothetical universalism.
[6] Martinius absented himself from a number of sessions, clashed with Gomarus, Abraham Scultetus and Sibrandus Lubbertus, and was close to walking out of the Synod.
