MANCHESTER — Bishop Peter A. Libasci of the Roman Catholic Diocese of Manchester has announced the following changes in parish assignments:

The Rev. Marcel I. Martel resigned as pastor of St. Rose of Lima Parish in Littleton and was granted a health leave by the bishop effective July 12. The Rev. Mark E. Dollard will take over as pastor of St. Rose of Lima Parish effective Oct. 6.

The Rev. Marc R. Gagne was appointed pastor of Good Shepherd Parish in Berlin and Holy Family Parish in Gorham effective Oct. 6.

The Rev. Edward J. Kelley was appointed temporary administrator of the Parish of the Assumption in Dover effective Sept. 19. He will serve in this position until a new pastor is named.

The diocese has also announced that the bishop will mark the opening of the “Year of Faith” by celebrating a pontifical Mass at St. Joseph Cathedral on Oct. 11 at 6 p.m. All are invited to attend.

The Mass will occur in concert with similar celebrations held throughout the world, including by Pope Benedict XVI in Rome.

The Year of Faith, announced by the Pope last year, will take place from October 2012 until November 2013. In his apostolic letter “Porta Fidei,” the Pope proclaimed that it should be a year for Catholics to walk through the “door of faith” and rediscover and renew their relationship with Christ and his church.
