To a degree, it makes perfect sense.
Just like when you speak to your children...you tell them about the birds and the bees - so they are aware of them...but, you don't go in to graphic detail...because that might lead to more trouble than had you said nothing to them, at all.
To be honest, the general public doesn't really care about all the nuances, the canons, the dogmas, etc. They want to hear about Christ and His teachings, and to them it is enough. Don't confuse them with something they don't understand, unless it becomes necessary.
This is why we always say "ask your priest"....because it is our clergy who know "more" than we do...and when we need that additional explanation, we go to them. It's not "hidden" from us, it's just not "pushed" upon us.
...for it is to those who are childlike that the Kingdom of the Heavens belongs... Matthew 19:14
