I’m a Catholic and I never go to English-speaking masses. I confess in Spanish, even though I know of a Catholic church here in the village that offers masses in English on certain days.
I’m not referring to all of Mexico, but anywhere that you go where there’s a Gringo community (and there are usually a lot of Gringo communities it in most places in Mexico), you’ll find that there’s usually an English mass.
Most people who move to this area in Lake Chapala or live in the villages here go to the Spanish-speaking mass, unless they’re that picky and have to have an English mass. The mass should be the same whether you’re in New York or in Mexico. Any Catholic coming to Chapala and Ajijic from New York or Texas can understand the mass although they may not understand every word because every Catholic mass is done in the same way.
If you’re a Protestant or an Anglican, there are churches here for you. For example, there are 3 - 4 different churches in Riberas del Pilar, in the Chapala Lakeside area.
When I go to mass in Ajijic, I see a lot of Gringos.
