Today is 01.Jan.2022. Is church mass limited to a certain number of parishioners? Is there social distancing because of Covid? Do I need to where a mask?

yes there was

Good evening, Francisco. At this time, we are not limiting the number of parishioners allowed at each Mass. We are not following any guidelines as far as social distancing is concerned nor are we enforcing wearing a mask. However, we encourage you to practice all safety measures including social distancing, mask wearing, and hand sanitizing when visiting the cathedral. If things were to change, we will announce it on our website, our fb page and with signs at the cathedral. If you feel more comfortable wearing a mask and practicing other safety protocols, please feel free to do so.
