Basil's significance for Eastern Christianity is not confined to trinitarian doctrine; he is equally important for shaping Eastern Christian monasticism itself. His Longer and Shorter Rules organized communal, rather than solitary, monastic life around shared prayer, work and obedience to a superior, a specific institutional choice that shaped the pattern later Eastern monasticism generally followed rather than leaving monks to pursue the solitary hermit's path some earlier ascetics had chosen.
Beyond doctrine and monastic organization, Basil built a large charitable complex outside Caesarea known as the Basiliad, combining a hospital, a hospice and a poorhouse under one single foundation, an institutional integration of medical care and poor relief that was itself unusual for its time rather than an ordinary extension of church charity.
Taken together, a trinitarian treatise, a monastic rule still followed in outline today, and a combined hospital and poorhouse complex describe a bishop whose influence reached well beyond the pulpit into how Eastern Christians would organize both their spiritual and their charitable life for centuries after his own death in 379.
