The Apostle again reminds the soul of the obscurity of the present life. We do truly know God, yet not with full clarity. Our understanding is like seeing a reflection in a dim mirror: real, but indirect and imperfect. The Fathers explain that in this life we know divine things through signs, images, Scripture, sacraments, and created realities. These truly reveal God, yet they do not allow the soul to behold Him fully as He is in Himself. Therefore all earthly knowledge should produce humility rather than pride. (St. John Chrysostom)

“We see now through a glass in a dark manner.” Augustine frequently teaches that the weakness lies not in God, but in us. The divine light is constant and perfect, yet our vision remains clouded by mortality, distraction, and sin. Thus the soul must be purified gradually. Charity itself purifies the eye of the heart, making the soul increasingly capable of perceiving divine things. The more a man clings to earthly loves, the less clearly he sees; the more he is detached from himself and united to God through charity, the more his inner sight is healed. (St. Augustine)

“But then face to face.” The Fathers speak of this with great reverence, for here the Apostle points toward the blessed vision of God in eternal life. This does not mean that the human mind will comprehend God completely, for the finite can never contain the Infinite. Yet the soul shall behold Him directly in a manner surpassing all earthly knowledge. Faith shall give way to sight, and the restless search of the soul shall finally come to rest in possession of the One whom it loves. (St. John Chrysostom)

“Now I know in part; but then I shall know even as I am known.” Augustine sees in these words the fulfillment of all holy desire. God already knows the soul perfectly, not from afar, but intimately and completely. In heaven the soul shall enter more fully into that communion for which it was created from the beginning. Every fragmentary understanding, every longing, every imperfect glimpse of truth in this life points toward that final union. Thus the Christian life is a journey from shadow toward vision, from partial knowledge toward fullness, and from faith toward the everlasting contemplation of God in charity. (St. Augustine)
