The '''Army of the Lord''', (Romanian: Oastea Domnului), is a spiritual and moral renewal movement in Romania founded, in 1922, by Fr. Joseph Trifa, a Romanian Orthodox [[priest]]. Fr. Trifa defined the Army of the Lord as a voluntary lay grassroots organization based on the Bible for revitalizing the Romanian Orthodox Church.
Controversy has surrounded the movement since its founding as Fr. Trifa's writings<ref>What is the Army of the Lord? (Ce
Este Oastea Domnului?)</ref> are silent concerning the role of the [[church]] and liturgy in salvation and spirituality. In his writings, his understanding of salvation and witness is expressed in language that is more commonly used by Western Protestantism. Thus, his ideas became objectionable to the hierarchy of the [[Church of Romania]] and resulted in his [[excommunication]] in 1936. Fr. Trifa reposed in 1937.
Since the fall of communism in the last decade of the twentieth century the course of the organization has been torn over issues about the purpose and mission of the Army of the Lord.
