we should frequently return our aspirations to him by means of the same messengers."

and charge him to pray in your stead."

St. John Vianney

Sometimes, a man's understanding is enlightened by an angel to know what is good, but it is not instructed as to the reason why ... But sometimes he is instructed by angelic illumination, both that this act is good and as to the reason why it is good."

St. Thomas Aquinas

St. Thomas Aquinas

"If a man is not rising upward to be an angel, depend on it, he is sinking downward to be a devil."

Samuel Taylor Coleridge

"Angels are spirits, but it is not because they are spirits that they are angels. They become angels when they are sent. For the name angel refers to their office, not their nature. You ask the name of this nature, it is spirit; you ask its office, it is that of an Angel, which is a messenger."

St. Augustine

"Both angels and demons are ignorant of the future, yet they make predictions. The angels do so when God reveals the future to them and commands them to prophesy, and what they prophesy comes to pass. Demons also make predictions, but these are only guesses based on what they see from afar."

John of Damascus
