In John 10:9, Jesus is quoted as saying, "I am the gate. Whoever enters through me will be saved." In Luke 11:9 is found, "And I tell you, ask and you will receive; seek and you will find; knock and the door will be opened to you." Revelations 3:20 says, "Behold, I stand at the door and knock. If anyone hears my voice and opens the door, (then) I will enter his house and dine with him, and he with me." Dom Albert Hammenstede O.S.B. noted that Porter was one of the minor orders. Herbert Thurston suggests that "the symbolism of this ceremony may also have been influenced by the old idea of seeking sanctuary".
