..well, because I said so!!!! that’s why!
Yes, this is EXACTLY Rome’s attitude!
Dogmas date into the time of the early church, and a lot of discussion went on as they worked out how to express what the church faithful believed.
but ordinary folk don't have time or energy or even the desire to get deeply into such things, so we go along with the core beliefs as expressed by the experts. We see God's goodness all around us, in our children, in the poor and sick, in science and nature, and in art music and stories.
God feeds us in the bread and wine. The family and marriage is holy because Jesus lived in a family. Parties echo the happiness of heaven. If we stray, we know that not only will Jesus forgive us but that he will seek us out like the good shepherd. And when we mourn, we know Christ will wash away our tears.
most Catholics learn about how God loves us and expects us to live by stories, not from quotations taken out of context.
Interpreting the bible for dogma without a PhD in Greek, history, and how the early church fathers taught what it means is sort of like the thinking of some people who eschew mainstream medicine and think they know more than those of us who studied 8 years plus 3 to 5 years of hands on training. lots of them on FR and all I can do is roll my eyes up in exasperation.
