In addition to Abbots Bromley School for Girls, this year's finalists were Ipstones Methodist Church from the Staffordshire Moorlands, and Berkswich Methodist Church and Rising Brook Baptist Church, both in Stafford.
Member of the judging panel Gavin Drake, the director of communications for the Diocese of Lichfield, which sponsors the competition, said: "Once again the standard of singing was excellent and it was very difficult for the judges to choose between the four finalists. But the quality of singing from Abbots Bromley's girls was extremely high and it is not surprise that they won. This justifies our decision to put them into the final rather than restrict them to the junior category."
Fellow judge, Lloyd Cooke, director of the Saltbox Centre in Stoke on Trent, commented: "What a privilege it was to help judge the competition and what a truly wonderful night of worship that the finalists put on together!"
Abbots Bromley School was founded by the Rev Nathaniel Woodard to provide education based on "sound principle and sound knowledge", firmly grounded in the Christian faith. The school's chapel is pivotal in school life and the girls have previously sung for BBC Radio Four's Daily Service and even at a Papal Mass in the Vatican. They will receive a crystal cross and a cheque for £500.
The school's director of music, Colin Walker, said: "Singing is at the very heart of so much of life at Abbots Bromley School for Girls both in chapel and beyond; it is very exciting that the commitment and enthusiasm of the girls has been recognised in this way. We are proud and honoured recipients of the Songs from the Aisles award for 2007."
The junior Congregation of the Year award went to a special choir established by Staffordshire Youth Service for a special event in Lichfield Cathedral. They too will receive a crystal cross and a cheque for £250.
Cllr Eric Drinkwater, the Cabinet Support member with responsibility for the Youth Service with Staffordshire County Council welcomed the award, saying: "The Youth Service is delighted that the youth Inspired event has received this prize. The young people who took part put in a great deal of hard work which was borne out by the performance.
"We knew that the standard was high, and this award shows just how talented and gifted those who took part are. We shall be asking the Youth Action Kouncil, which represents young people from across the county, how the money should be used."
