One resource I'll mention, even though it is not strictly speaking an Orthodox publication, is the
Ancient Faith Study Bible. It is a Protestant Bible in terms of the scope of books included, and the translation, which is the
(Holman) Christian Standard Bible (CSB). But the overall content of the Study Bible is exclusively commentary from the early Church Fathers. It includes only Church Fathers from the 1st through the 8th century, so it is pretty much by definition only those who would be part of Orthodoxy.
Apart from the commentary, there are articles on various theological topics, and the text of those articles are also taken directly from the writings of the Church Fathers. Then there are brief biographies of the Church Fathers who are quoted, some brief articles on various heresies, and also intermittent quotations taken from St. Augustine's Confessions.
All of the commentary is directly taken from the massive
Ancient Christian Commentary on Scripture series edited by Thomas Oden. So this Bible is a nice and very economical way to get access to a pretty extensive selection of materials from that series.
As it is edited by Protestants, there was no doubt some bias in the selection of commentary, as well as some noticeable lacunae and silences on important passages. For instance, in the commentary on John chapter 6, they do not include any commentary that would support the idea of the real presence in the Mystery of the Eucharist etc. Something to keep in mind, but not a reason to avoid using this as a nice reference Bible.
Finally, a quick word about the translation itself. The
CSB is a modern, conservative translation. It aims to be readable like the NIV, and not as hard-core literal / clunky as, say, the NASB. It's not one of my preferred translations, but it is superior to the NIV. The other interesting things about the CSB is that it is a totally new translation that did not piggy-back off of the KJV lineage as most translations have done (NKJV, Revised Standard Version, NRSV, etc etc.) So for those looking for a separate point of reference completely outside of the KJV lineage, this is not a bad Bible to refer to.
The Church Father commentary is what makes this Bible valuable, and it is very reasonably priced. For a non-Orthodox publication, it is very well done as far as trying to present only the early church teachings and writings.
