New Credo Podcast: Do the Father, Son, and Spirit work inseparably? Simply Trinity (Part 5)

In  this episode of the Credo Podcast, Matthew Barrett fields questions from Samuel Bierig about his new book, Simply Trinity: The Unmanipulated Father, Son and Spirit (Baker).

They consider what it means for the Spirit to “proceed” eternally from the Father and Son. They also consider the biblical language used, from “gift” to “love,” to capture the Spirit’s procession.

Barrett then turns to one of the most important trinitarian doctrines: inseparable operations. Barrett warns against describing the unity of the Godhead merely as a cooperation and advocates instead for that ancient motto: the external operations of the Trinity are indivisible. After a discussion of “appropriations,” Barrett turns to John Owen to identify how we can have communion with Father, Son, and Spirit.
