Mieczkowski, Janusz (Polskie Towarzystwo Teologiczne, 2009)
In the first centuries of Christianity the Holy Mass was celebrated once a day only, also on Sundays. From V century it became necessary to celebrate more Masses in the same day because communities expanded and their members weren’t able to participate together in just one Holy Mass. The Main Mass (High Mass) usually was established between 9 and 11 in the morning. This Mass offered for the parishioners was celebrated by a pastor very solemnly with festive singing. It had the best liturgical things, garments, aspersion and processions, along with a sermon followed by special prayers for the dead.
