This past weekend at Eastbrook, I stressed the importance of the Trinity in the first part of my message entitled “Worshipping” in our series “Living Church” on Acts 2:42-47. There are some things in our faith that I would consider secondary, but the Trinity is not one of them. The Trinitarian understanding of God – one God in three persons of Father, Son, and Holy Spirit – is at the core of our faith as Christians.
As Bruce Milne writes in his book, Know the Truth:
Just about everything that matters in Christianity hangs on the truth of God’s three-in-oneness.
Or, to hear from an ancient commentator, Origen writes:
The believer will not attain salvation if the Trinity is not complete.
Since I didn’t give as much time to fully addressing the Trinity as possible, and because I am limiting my preaching largely to references found within Acts, I wanted to post an a couple of additional resources here. The following two resources can be downloaded as PDFs below and are from my time at Elmbrook Church, when I taught the session on the Trinity in the New Members class:
- The Trinity Explained (teaching notes) – don’t like the title of this but it is what I was given
- The Trinity – historical background – a sweeping overview from the time of the New Testament to Karl Barth on the Trinity with many great thinkers overlooked
