1) There were seven candles on the menorah
2) In The Shape of the Liturgy by Dix, he says that the 7 candles might have been inspired by the account in the Apocalypse (The book of Revelation) to "give a Christian turn to the old secular emblem. The bishop is the earthly representative of Christ as the Eucharist is the earthly manifestation of heavenly worship and the adaptation would easily suggest itself."
3) Atchley says, "The number of the seven candles borne before the Pope was probably derived from the Book of the Revelation. One cannot help noticing a similarly between the heavenly worship therein described and parts of the ceremonial of solemn Mass at Rome. We are told of a 'throne set in heaven, and one sat on the throne...And I saw in the right hand of him that sat on the throne a book': and under the altar the souls of them that were slain for the Word of God/Angels and the elect clothed in white robes' stand about the throne , singing to God and the Lamb.
4) The number seven also play in with the original seven ecclesiastical "districts" linked to Pope St. Fabian. they had seven bishops, deacons, and subdeacons.
5) In the commentaries of the Middle Ages it was common to link them to Temple worship, or with the "sevenfold" priestly virtue" or the seven angels or the Holy Spirit and his seven gifts. taken from the Catholic Answers forum
