"In the radio blackout, I opened the little plastic packages which contained the bread and the wine. I poured the wine into the chalice our church had given me. In the one-sixth gravity of the moon, the wine slowly curled and gracefully came up the side of the cup. Then I read the Scripture, ‘I am the vine, you are the branches. Whosoever abides in me will bring forth much fruit.’ I had intended to read my communion passage back to earth, but at the last minute Deke Slayton had requested that I not do this. NASA was already embroiled in a legal battle with Madelyn Murray O’Hare, the celebrated opponent of religion, over the Apollo 8 crew reading from Genesis while orbiting the moon at Christmas. I agreed reluctantly…Eagle’s metal body creaked. I ate the tiny Host and swallowed the wine. I gave thanks for the intelligence and spirit that had brought two young pilots to the Sea of Tranquility. It was interesting for me to think: the very first liquid ever poured on the moon, and the very first food eaten there, were the communion elements.”
NASA kept this secret for two decades. The memoirs of Buzz Aldrin and the Tom Hanks’s Emmy- winning HBO mini-series, From the Earth to the Moon (1998), made people aware of this act of Christian worship 235,000 miles from Earth.
