Fr Laurence Soper, 72, is accused of assaulting five boys, one under 14 at the time, over a period from 1972 to 1986.
The nine charges include offences of buggery, gross indecency and indecent assault.
He was arrested as he arrived at Luton Airport on Sunday by officers from Scotland Yard's Sexual Offences, Exploitation and Child Abuse Command.
Police had been hunting for him for five years and he was eventually detained under a European Arrest Warrant in Kosovo in May.
He will appear at Ealing Magistrates' Court on Monday.
Four of the charges, including buggery, gross indecency and indecent assault, relate to a single alleged victim and date from February 17, 1972 to February 18, 1976.
The boy was aged under 14 when Soper carried out an act of gross indecency against him, it is alleged.
Two charges of indecent assault relate to a second boy aged under 16 alleged to have occurred between 22 August 1979 and 23 August 1984.
Soper faces charges of indecent assault against two further boys under 16, alleged to have taken place between 4 December 1979 and 23 December 1984, and 10 November 1979 and 11 November 1984.
A fifth boy aged under 16 was assaulted on a day between 14 May 1982 and 15 May 1986, it is alleged.
