Brad Birzer writes on Oak trees as a symbol of free peoples:

One of the most fascinating symbols of a republic in the western tradition, from the Romans through the Germanic Barbarians to the American founders to the American founders of the Republican Party, is the mighty oak. As noted in the previous essay on the history on the rise of the modern nation state, all republics must exist—by their very nature—as reflections of nature herself. They are, at essence, organic, necessarily experiencing birth, middle age, and death. How easily one might transfer this to the oak, thinking of its own stages, from acorn to prevailing gian, to corrupted and hollowed-out shell. …

When the greatest of Roman republicans, Marcus Tullius Cicero, offered the world the first treatise on the natural law, On the Laws, began with the image of an oak, deeply rooted not just in the soil, but in the poetic imagination itself. “I recognize that grove and the oak tree of the people of Arpinum: I have read about them often in the Marius. If that oak tree survives, this is surely it; it’s certainly old enough,” Atticus begins. To which Quintus famously answers, “It survives, Atticus, and it will always survive: its roots are in the imagination. No farmer’s cultivation can preserve a tree as long as one sown in a poet’s verse.” Indeed, Quintus continues, this very oak might have been planted by the one god. Certainly, the name of the oak will remain, tied to the sacred spot, long after nature has ravaged it.

In his History of Early Rome, Livy informs us that a consecrated oak sheltered the praetorium, a seat of waiting and contemplation for foreign guests and ambassadors from the Senate. Likewise, Suetonius reminds us that Mars, especially, favored the oak as a tree symbolizing the divine authority.

The Mediterraneans, though, held no monopoly over a mythic understanding of the oak, as the Germanic tribes far to the north considered the tree the symbol of their god of justice, Thor. When the Anglo-Saxons and Scandinavians met to decide the fate of inherited and common law–which laws to pass on, which laws to end, and which laws to reform–they met as a Witan or AllThing under the oaks.

Christians, knowing the oak to be so utterly rooted in the pagan tradition, knew not whether to love or to hate the tree. According to St. Bede, when St. Augustine of Canterbury called a conference of church leaders in 603, he did so at an oak, knowing the Anglo-Saxon fondness for the tree. There, at what became known as Augustine’s oak or Augustine’s Ak, the evangelist called for unity in proclaiming the gospel. Two generations earlier, Bede records, St. Columba had done something similar, building a monastery among the Celts known as Dearmach, “Field of Oaks.”  Even at the most famous of medieval monasteries, Lindisfarne, Finan built the church altar there not out of traditional stone, but, rather according to the custom of the peoples in that region, an altar “of hewn oak, thatched with reeds.”

When St. Boniface, a century later, encountered a group of Friesians still worshipping the oak of Thor, he—with nothing short of awesome bravado–attacked the tree with his axe. According to the hagiographic legends surrounding Boniface, the oak exploded into four parts moments before the blade touched its bark. So astounded were the pagans at his daring, that St. Boniface seized the moment to begin proclaiming the gospel. Where the ruined oak stood, according to hagiographic myth, an evergreen grew in its place. As it was getting dark and Boniface continued to preach, his followers placed candles all around and upon the evergreen, thus creating the first Christmas tree. …

If Boniface undid the oak as a direct representation of a god, he could not undo its importance to justice, as it remained a symbol of the law and of a free people. When the grand Christian King Alfred the Great met with his men in the late 800s to judge the inheritance of the common laws of the Anglo-Saxon people, they, too, met under an oak. Critically, Alfred and his Witan judged the laws. They did not create them, believing such actions illegal. A ruling body can only judge what it has inherited, not create laws out of nothing. Such a power belongs only to God and through his people only across time. …

The symbol of the oak remained a powerful one in colonial America, especially as the various communities on the eastern seaboard continued their own observance of the traditional common laws and, especially, in their Declaration of Independence. Though not exclusively oak, oaks made fine Liberty Poles and Liberty Trees in the 1760s through 1780s, and newly-freed American communities regularly planted oaks to celebrate their independence from Britain. Pamphleteers, not surprisingly, used the symbol of the acorn and the oak as representative of America’s independence and hardihood.

When Congress rashly passed the democratic Kansas-Nebraska Act in 1854—a law that claimed that the enslavement of an entire people could be decided by mere majority vote—angry republican citizens of Michigan formed a third party, the Republican Party, in Jackson, Michigan, under, not surprisingly, a grove of oaks.

Whatever one in the early twenty-first century might think of Jupiter or Thor, the oak remains a mighty symbol of a free people, a people ready to remember and reclaim what is rightfully theirs by the grace of the Creator and the created order. The oak reminds us of strength in the face of nasty and bitter times, returning us to the nourishment of what makes us strong and free, the duty to govern ourselves in a fashion becoming to God and nature and, equally important, to the dignity of the human person. Unlike oppressive governments who rely on cults of personality, the republic relies on the nature of nature and the nature (good and bad) of the human person.

This perspective on Oaks spoke to me because the Sugar Creek Valley in Armstrong County, Pennsylvania is a home to White Oaks, and there are a number on the acres that my family settled there in the early 1800s.

Trees matter.
