I was using Google Maps to look at a medium-sized city in Nigeria (because work) and spotted Absorption Cathedral. I tested it out on six browsers on two computers at work and home. Microsoft Edge, Google Crome for Windows at work and Google Chrome, Safari and Internet Explorer for Mac at home call it Absorption Cathedral. Internet Explorer for Windows at work calls it Assumpta Maria Cathedral (as does Bing Maps for Mac at home). The diocese’s own website call it Assumpta Cathedral (as do Wikipedia’s pages for the diocese and the cathedral) and there are results online for Maria Assumpta Cathedral.
I can understand that Google Maps displays differently on different browsers, but would have assumed (<haha) that it uses the same data for each. The Roman Catholic Church is a major international organisation, so the information must be readily available. A number of travel websites show accommodation near Absorption Cathedral.
Absorption and assumption have similar meanings (ab- + sorbēre to suck in, swallow and ad- + sūmere to take up). Assumption has been given a theological meaning, but absorption hasn’t.
PS The Borg on Star Trek was/were at the back of my mind, but the word used there is assimilation.
