John C. Herbert was admitted to the Virginia bar and commenced legal practice in Richmond. He pursued higher education at St. John's College before delving into law. Herbert's family had a notable background in commerce and landholding, which influenced his advocacy for policies supporting local merchants, trade, and property rights. He married into a prominent Maryland planter family, further embedding him in the region's socio-economic fabric. His leadership roles and legal expertise laid a foundation for subsequent public service endeavors.

John C. Herbert's political identity is marked by a blend of local economic advocacy and a nuanced stance on property rights, shaped by his family's mercantile background and legal expertise. He champions policies favoring local merchants and trade, yet his involvement in property litigation over the Northern Neck Proprietary suggests a calculated approach to regional economic interests. His social engagement, particularly in establishing a local church, indicates a community-focused strategy, though the absence of specific environmental stances leaves a notable gap in his policy portfolio.
