A number of conditions must be respected for the liturgy: firstly, a place such as a church, chapel or any other place approved by the Church authorities, a place that is well prepared, quiet, clean and dignified; secondly, the hours such as morning and evening prayers, the Paschal Tridium; thirdly, the day such as daily prayer or Sunday, there are also days that are ordered to be sanctified.
