By Dr. Stacy Trasancos, Catholic Answers - Some argued that because Christ appeared through shut doors to his disciples, and vanished before their eyes appeared in different shapes, that his body was only an image. However, Christ himself addressed these objections. When Christ appeared to the disciples and they thought they were seeing a spirit, he told them to “handle and see” his body. He was not just observable to the disciples, but also touchable and living. Scientifically speaking, there is no stronger proof that someone exists than to be able to touch the person and observe him living.
