This work examines the problem of how to connect the historic doctrine of the Trinity to Christian devotional practice. Two criteria for a successful Trinitarian spirituality are proposed: that of drawing significantly from nuances of the classic formulations of the doctrine and dealing with the mode of original Trinitarian self-disclosure, that is, the unfolding biblical doctrine of the historia salutis. Various historical attempts at articulating a method are examined, with special emphasis given to the Puritan John Owen.
