Abakholwayo abangena ezindaweni ezazingenabantu enyakatho yeNew Spain babenombono wokuguqula izizwe "eziyizihambi" zenze ubuKristu futhi ngaleyo ndlela bazihlanganise nempilo yezepolitiki, ukuze kamuva kutholakale izikole nemizi emadolobhaneni asungulwe yiwo.
Ukufeza lezi zinhloso, abazali, njalo bephelezelwa ngamaqembu ahlomile, baya kwabeZizwe babanikeza ukuvikeleka eSontweni naseNkosini yaseSpain ukuze bathole imfundo yobuKristu. AmaNdiya amukela, ahlangana ukuze akhe imishini, abe yisiphephelo samaNdiya nendawo yokufunda izindlela zaseYurophu zezolimo neminye imisebenzi.
Lapho ukuthula sekuphelile, ukuthunywa kwaba yidolobha elincane elinesonto, ngenkathi izithunywa zevangeli zathuthela kwenye indawo ukuqala kabusha umsebenzi wazo wobuvangeli. Lolu hlelo lwaluyingozi, ngoba impela amaNdiya asenyakatho abeka ukumelana okuthile, ngoba ayenobutha kakhulu kunalawo ayesenkabeni, abalekela ngasezintabeni.
Ukuguqulwa kwasebenza ngesisekelo somklomelo womhlaba nokuvikelwa kwamaNdiya ngokushintshana ngokulalela. Labo ababephikisa babejeziswa, kuyilapho labo ababehlela ukuvukela babulawa.
Lapho nje isizwe sendabuko sesihlanganisiwe, i-nucleus eyinhloko noma inhloko yayihlanganiswa, eyayakhiwa ngamadolobha amaningana nemifula eyayingaphansi kwayo. Izithunywa zevangeli zazihlala echibini futhi zaziphethe okungenani amadolobhana amabili avakashile. Izithunywa zevangeli ezintathu noma ngaphezulu zazincike kumphathi kanye nasivakashini sendawo. Lezi zikhungo ndawonye zenza isiFundazwe.
Okokuqala, kwakhiwa isonto elenziwe ngamatshe futhi lazungeza, nge-adobe, izindlu zakhiwa ama-friars ayezoshumayela, ilanga, amadayisi nemindeni yabomdabu, futhi ngokuvamile isikole. Ezikhungweni kwakukhona lokho esasingakubiza ngohlaka lwezomnotho lwakudala. Babenezindawo zokutshala, ukuhlwanyela umhlaba, ukuvula imigwaqo nemisele yokunisela; ukukhulisa imfuyo, imifino kanye nomsebenzi wobuciko. Kwakufundiswa iCatechism, ukufunda, ukubhala nomculo ezikoleni.
Ngokuhamba kwesikhathi, eminye imishini yashiywa ngokuphelele ngenxa yezehlakalo ezahlukahlukene, njengokuxoshwa kwamaJesuit ngo-1767, ukusabalala kwezifo ezalethwa abaseSpain, ukuhlaselwa amaNdiya "angaphandle", isimo sezulu, amabanga amade nemali encane ukuyondla. Amanye agcinwa namuhla njengamasonto kanti amanye manje enza abantu ababaluleke kakhulu. Kodwa-ke, kweminye imisebenzi kuphela isiza sendawo ababekuyo kuqala siyaziwa futhi kwezinye kusele amanxiwa kuphela.
AmaJesuit asungula imishini eBaja California Norte naseSur, eSonora, eSinaloa, eChihuahua, enyakatho yeNayarit, okuyingxenye yeDurango naseCoahuila. Ngemuva kokuhamba kwabo, amaDominican ahlala enyakatho yeBaja California, kanti amaFranciscans ashumayela iTamaulipas neNuevo León futhi athatha isikhundla sezithunywa zevangeli ze-Order of Loyola engxenyeni eseningizimu yeBaja California, Sonora, Sinaloa, Chihuahua, Nayarit, UDurango noCoahuila. Enyakatho maphakathi nendawo, ngemuva kokuhlubuka kwamaZacateco —okuyinto eyavimbela ukuthunywa kwamaFranciscan ekuqhubekeni—, abomdabu bazihlela baba yizindela.
Ngo-1563 uCaptain Francisco de Ibarra wahambela le ndawo ehlanganisa isimo samanje saseSinaloa futhi wasungula amadolobha athile. Kodwa-ke, lokhu akuzange kuhlale isikhathi eside futhi kwaze kwaba ngo-1591 lapho ngemiyalo yombusi waseNueva Vizcaya, obaba abangamaJesuit uGonzalo de Tapia noMartín Pérez bathunyelwa ukuba bashumayele lesi sifunda.
Abenkolo bawela iSierra Madre Occidental ngoMeyi walowo nyaka, bangena nge-Acaponeta, eNayarit, badlula eCuliacán bafika kule ndawo, lapho ngoJuni 6, 1591 basungula khona ibhilidi labo lokuqala: iSan Felipe de Sinaloa.
