It is well documented that 20 years after Neil Armstrong and Buzz Aldrin landed on the moon that on of the first things done by Buzz Aldrin was to participate in a private and personal communion service.

The Lord’s Supper, consisting of the elements –bread and the fruit of the vine– is the symbol expressing our sharing the divine nature of our Lord Jesus Christ (2 Peter 1:4 [KJV/NIV]), a memorial of his suffering and death (1 Corinthians 11:26 [KJV/NIV]), and a prophecy of His second coming (1 Corinthians 11:26 [KJV/NIV]), and is enjoined on all believers “till He come!”
