400 Irish priests claim new Mass translation is ‘elitist and sexist’

[Vetus Ordo]

no soy digno de que entres en mi casa pero una palabra tuya bastará para sanarme

A better translation from the original Latin would be:

"Señor, yo no soy digno de que entres en mi techo (o morada), mas dí una sola palabra y mi alma será salva."

I think that "bajo" (under) mi techo, would be a better translation, than "en" (in, or on, maybe), no?

Yes, you're correct.
