Jenaro Sánchez Delgadillo was a Mexican Catholic priest born in 1886 in Zapopan. Serving within the Archdiocese of Guadalajara, he was recognized for his humble nature and his dedication to teaching catechism and caring for the sick. During the Cristero War, a period of intense conflict between the Mexican government and the Church, he continued to perform religious services in secret. His commitment to his faith led to his execution by the military in 1927, after which he was recognized as a martyr.
