St. Peter of Cetinje was born on April 1st, 1749, in the village of Njegushi, and became a monk at the age of twelve. In 1782, he became both Metropolitan and ruler of Montenegro. This holy man devoted his whole life to his people. Within Montenegro, he worked with his all strength to pacify the warring clans and established the first Montenegrin Code of Law. Externally he tirelessly defended Montenegro and its people against the plundering onslaughts of enemies. The semi-autonomous region of Brda (the Highlands), whose inhabitants supported him in his struggles, was finally incorporated into Montenegro during his life-time. St. Peter was strict with himself, and just and humble towards others. He lived a life of prayer in one tiny cell as a simple monk, although he was the ruler of a country. With his steadfast faith, love, patience, purity, meekness, and good works, he was able to pacify a stubborn and unruly people, who had hitherto refused to submit even to the mightiest powers on earth. He entered into rest on October 18th, 1830, at the age of 81. His myrrh-streaming relics are preserved incorrupt in the monastery of Cetinje. The Lord glorified him both in heaven and on earth as His true and faithful servant.

Consonant with the Great Commission of our Lord Jesus Christ (Matthew 28:19-20), the principal goals of St. Peter of Cetinje Orthodox Missionary Brotherhood are to encourage, support, foster, promote, and facilitate the establishment and/or growth and development of Orthodox Christian communities in the Greek Orthodox Archdiocese of Mexico, Central America, Colombia, Venezuela, and the Islands of the Caribbean, thereby incorporating individuals into the fullness of the life in Christ.
