Congrégation de l'Oratoire
Sánchez was born in New Spain (today's Mexico) and studied at the Royal and Pontifical University in Mexico City. He sought teaching positions but did not get them. On various occasions he served as chaplain of the chapel of Our Lady of Los Remedios, and in 1662 he joined an archconfraternity of secular priests which was later constituted as the first Oratory of Saint Philip Neri in Mexico.
