The Reverend Lawrence Hilditch stepped down voluntarily from his duties minister of Castlederg and Killeter churches in January 2005.
It followed a complaint made by a member of his congregation.
Investigations by the police and the church have concluded that the matter should not be taken further.
Mr Hilditch was first installed as a minister in Moy, in 1994, moving to Newtownards in 2000. He went to Castlederg towards the end of 2003.
