Mass is not the time for catechism, it is the time for worship.
Likewise a sermon is not meant to be a lecture, they are two different distinct forms of oratory, or at least are meant to be.
You should have been taught these things as a child by your parents, and if they are still alive you can ask them as an adult to, they are your primary guides in the Faith.
It is OUR responsibility once we become adults and it is up to us to MAKE time and to ATTEND the classes if they are available and we think they would be helpful to us.
There are also many many books available on everything Catholic, or you can just ask your priest when you socialise with him OUTSIDE of Mass, but at Mass concentrate on worshipping God as that is what you are there for.
[Edited] It’s this mentality that needs to be done away with. There are many issues with what you wrote, but the most important issue is that you are thoroughly
wrong. The Church has never taught that mass has this exclusivity you are [edited] ranting about. The liturgy of the mass is the procession and culmination of many aspects of the Christian life - prayer, worship, and communion, as well as
instruction and explanation. As the poster who immediately responded after your mind-numbing barrage of baseless rules and regulations, the very Church you claim to be representing has resoundingly dismantled your exhortations, and She did so in the 16th century at the Council of Trent. How about going back a little further? Origen, one of the Church Fathers, also seems to disagree with you, and he did so 1,800 years ago.
From
NewAdvent.org on the Homily:
“It is the
oldest form of preaching…It was the kind of preaching that was
used by the Apostles and Fathers in addressing the faithful…In the “First Apology” of Justin Martyr (c. lxvii) we read: “
On the day called Sunday, all assembled in the same place, where the memorials
apomnemoneumata] of the Apostles and Prophets were read . . . and when the reader has finished,
the bishop delivers a sermon”, etc. In this connexion, the “Encyclopaedia Britannica” (ninth edition) says: “The custom of delivering
expositions or comments more or less extemporaneous on
the lessons of the day at all events passed over soon and readily into the Christian Church” *.”
“Origen has been called the father of the homily; it was he who contributed most to popularize this species of literature in
which are to be found so many instructive details on the customs of the primitive Church, its institutions, discipline, liturgy, and sacraments.”
“Since Origen’s time homily has meant, and
still means, a commentary, without formal introduction, division, or conclusion, on some part of Sacred Scripture,
the aim being to explain the literal, and evolve the spiritual, meaning of the Sacred Text.”
Maybe do a little research before trying to pass off your [edited] words as fact.*
