“The Fathers of the Church taught that there are guardian angels of nations, countries, churches, as well as of individuals (Rev. 2). Yea, even of elements, stars and planets. St. John of the “Ladder” testifies of his personal guardian angel: ‘Whenever I was longing for a greater advancement in spiritual life, the angel appeared in such a case and enlightened me.’”
(St. Nicholai Velimirovich on ‘The Lord’s Prayer’)
