An Orthodox Catechism by Fr. Josiah Trenham
This 16-part audio series offers a full-orbed introduction to Orthodox Christianity. It has been used for over 20 years to prepare dozens of catechumens for the Church. You can start listening for free on Patristic Nectar's site: https://app.patristicnectar.org/discover/catechism/an-orthodox-catechism . You will need to sign up before you are able to listen.
This was personally recommended to me by my Priest who was leading my Catechism. The episodes are very informative, very engaging, and serve as a really good introduction to the Orthodox Church and various aspects of it.
The Lord of Spirits: The Seen and Unseen World in Orthodox Christian Tradition
The modern world doesn’t acknowledge but is nevertheless haunted by spirits—angels, demons and saints. Orthodox Christian priests Fr. Andrew Stephen Damick and Fr. Stephen De Young host this live call-in show focused on enchantment in creation, the union of the seen and unseen as made by God and experienced by mankind throughout history. What is spiritual reality like? How do we engage with it well? How do we permeate everyday life with spiritual presence? The live edition of this show airs on the 2nd and 4th Thursdays of the month at 7pm ET / 4pm PT.
The episodes are roughly 2-3 hours, so these are a bit lengthier. But this is a highly recommended podcast that tackles a wide variety of topics. Some topics are across multiple episodes, others are more standalone. Some particular episodes I've seen recommended:
How (and How Not) to Read the Bible: Reading the Bible is easier now than in any previous moment in history. And misreading it is also the easiest it’s ever been. What does it mean to read the Bible historically? To read it literally? What are some interpretive/hermeneutic ideas that don’t make sense if you look closely at them? Join Fr. Stephen De Young and Fr. Andrew Stephen Damick as they go “meta” for this episode and talk about what it means to read the Bible as Orthodox Christians.
The Priest Shall Make Atonement: "Atonement" is a word invented for the translation of the Bible into English, because there was no good English word for the concept it describes. So what does it mean? People have atonement theories. Is atonement purely theoretical? Does it have anything to do with suffering or punishment? And who or what is atoned for?
The Mountain of God and the Boat of Theseus: The Scriptures speak of what we might call spiritual places—sacred geography—the Mountain of God, Heaven, Paradise, the Underworld. Are these imaginary places? If not, how does one go there? In this first of two episodes on sacred geography, Fr. Andrew Stephen Damick and Fr. Stephen De Young begin a fantastic voyage into another world.
The Lord of Spirits Goes to Hell: With this Holy Week / Pascha special episode, Fr. Andrew Stephen Damick and Fr. Stephen De Young take a close biblical look at what happens when the Lord of Spirits Himself journeys into the underworld to set his people free.
You Are the Christ, the Son of the Living God: What does it mean that Jesus is the Messiah? What were the apostles saying when they said that, identifying Him as the Christ? Find out the weight behind their words with Fr. Stephen De Young and Fr. Andrew Stephen Damick.
The Whole Counsel of God: An Introduction to Your Bible
If you are looking for an in-depth Bible study podcast then The Whole Counsel of God: An Introduction to Your Bible comes highly recommended by a lot of people. Each episode takes a very small section and dives into it. The episodes themselves aren't super long (generally under 30 minutes) so it's relatively easy to slot into your schedule. While each episode follows on from the last, you absolutely can just hop in to whatever episode you would like.
There is also a book by the same name which aims to clear up some misconceptions people have about the role of the Bible in the Orthodox Church. Including addressing topics such as inspiration, inerrancy, the formation of the biblical canon, the various texts and their provenance, the place of Scripture within Orthodox Tradition, and how an Orthodox Christian should read, study, and interpret the Bible.
Light Through the Past: A Survey of Church History
This podcast will look at the course and development of the Orthodox Church, its struggles with heresy, the empire, and relations to other Christian bodies.
Glory to God: Thoughts and reflections on Orthodox theology and life
Fr. Stephen Freeman is a retired Archpriest of the Orthodox Church in America and resides in Upstate South Carolina. He is the author of Everywhere Present: Christianity in a One-Storey Universe, and Face to Face: Knowing God Beyond Our Shame, as well as the popular Glory to God for All Things blog. His blog has quickly become one of the most read Orthodox blogs, being translated frequently in Romanian, French, and Serbian, by enthusiastic readers. You can check out the podcast here.
Search the Scriptures Live: Interesting and Accessible Bible Study for Busy People
Presbytera and Dr. Jeannie Constantinou guides us through Holy Scripture with the eyes of the Church Fathers and answers listener questions in this edition of the Search the Scriptures podcast recorded live.
I would say Ancient Faith Ministries is where a lot of the high quality podcasts are hosted. While I don't rule out the potential for a podcast here or there to perhaps have content you disagree with politically (I have not listened to every podcast), I feel like the site is relatively safe for just picking a random podcast that sounds interesting. You can always try googling the name of the podcast to see if people have made any comments about views shared on it if you want to be on the safe side.
