Firstly, I only searched for and copied passages which mention the Father as the first cause, the ultimate cause of all things, the cause of the Son or Spirit, passages which, for instance, identify the Father being without cause with His exclusive property of being unbegotten, etc. In other words, there are many more passages I could have quoted, passages which instead speak of, say, the Father's uniqueness in terms of origination, sourcehood, or beginning, or how the Son's or Spirit's being or existence is from, of, or otherwise derived from the Father. I just found it convenient to hone my search in terms of causation.
Further, I only researched books found on http://newadvent.org/. I am aware of at least one book not on that website which contained statements which would have otherwise qualified, but I did not intend for this to be comprehensive. That wasn't the point. The point of the document is simply to show how pervasive this doctrine was in the early church.
Any edits I made in the above document were either grammatical - in changing the font and type for better readability, some errors occurred and a few have probably been missed - or because newadvent includes Scriptural quotations not found in authors' original works. People are welcome to compare my edit to the online version, there is no significant difference.
Now, I don't usually research church history, but Sean Gerety rekindled my interest after recently peddling the same embarrassing canards on facebook he did when we discussed Trinitarianism several years ago, including this one:
I find it offensive that you think we're stupid, when even a toad could tell that no Trinitarian could ever write as you have: "The Son and Spirit are not “autotheos.” FWIW I'm not going to revisit this whole sorry affair, but suffice it to say you're not a Christian. You may not like Unitarian or Arian, but you is what you is.Sean is now free to consider Alexander of Alexandria, Athanasius, Basil, Clement of Alexandria, Cyril, Eusebius, Gregory Nazianzen, Gregory of Nyssa, Gregory Thaumaturgus, Hillary of Poitiers, Hippolytus, Irenaeus of Lyons, John Chrysostom, John of Damascus, Justin Martyr, Novatian, Origen, Rufinus, Tertullian, Theodoret, etc. as anti-Trinitarians and less intelligent than toads.
