Students at Union Theological Seminary prayed to a display of plants set up in the chapel of the school, prompting the institution to issue a statement explaining the practice as many on social media mocked them. "Today in chapel, we confessed to plants," the nation's oldest independent seminary declared Tuesday on Twitter. "Together, we held our grief, joy, regret, hope, guilt and sorrow in prayer; offering them to the beings who sustain us but whose gift we too often fail to honor. What do you confess to the plants in your life?"
