Q. 1.What are the names of the seven Archangels?

A. 1. The United States Catholic Conference of Bishop website quotes Saint Gregory, one of the Doctors of the Church and Pope, who says they are:

Michael,
Gabriel,
Raphael,
Uriel,
Phanuel,
Zarachiel,
Simiel.

The Holy Bible also tells us that Lucifer is a fallen Archangel.

The Eastern Orthodox Church has a slightly different list of Archangels. They are:

Michael,
Gabriel,
Raphael,
Uriel,
Segudiel,
Selaphiel,
Barachiel.
