This is not a pantheon inherited from antiquity. It is a working order of powers that formed in the last century or so, inside Catholicism rather than beside it, and its logic is the logic of patronage.
Above it stands the God of the Church, together with the recognised saints and the Virgin under her Mexican title. That level is not in dispute and is not what distinguishes this entry. What distinguishes it is the layer beneath: figures who receive real devotion, real shrines and real offerings, and who have not been canonised and in several cases never will be.
Santa Muerte, personified death, is the most visible and the fastest growing, addressed for protection, healing, love and for outcomes the official cult will not be asked about. Jesus Malverde is venerated in Sinaloa as a bandit executed at the start of the twentieth century. Juan Soldado is venerated in Tijuana by people crossing a border, having been executed for a crime his devotees hold he did not commit.
The pattern is consistent. These are the dead who were failed, or who operated outside the law, elevated by popular acclaim rather than by any authority, and approached for the things people cannot take to a priest. The route in is elevation of a human being by the devotion of other human beings, with no institution granting it and one actively opposing it.
