“Whether the angels will do anything towards the resurrection? ... This ministry will be exercised chiefly by one Archangel, namely Michael, who is the prince of the Church as he was of the Synagogue (Dan. 10:13,21). Yet he will act under the influence of the Virtues and the other higher orders: so that what he shall do, the higher orders will, in a way, do also. In like manner the lower angels will co-operate with him as to the resurrection of each individual to whose guardianship they were appointed: so that this voice can be ascribed either to one or to many angels.” St. Thomas Aquinas, Summa Theologica, Supplement, Q. 76, Art. 3
