@Thomas,
I wonder if you are/were Catholic or Evangelisch. (there is no correct translation for this. Protestant is to wide)
I grew up in a pure Lutheran country and the Swedish Lutheran Church is very close to the Catholic Church.
I cannot remember exactly what was discussed or not, but we did learn about creation, Virgin Mary and Jesus died and rose for us.
As the Lutheran church is interested in symbols all this is taken more serious than in the German Evangelische - reformed church - where the pastors have very little or no interest in the symbols, the colors of the liturgical year etc.
The Lutheran churches have a crucifix and the Evangelische a cross.
Almost every Swedish church has a Statue of the Virgin Mary. Where I live we even have a church dedicated to Mary, her symbols are everywhere the colors are her symbolic colors.
Another church which has some Catholics who participate in the church service has now a special Statue of Virgin Mary by the entrance, so the Catholics can pray to her before leaving the church. This was a wish of the Catholics.
This would never happen in an Evanglische Kirche.
It is not unusual in our Lutheran Church to see people kneel when praying,
we make sign of the cross during service.
I think the basis of religious instructions were to support our believes in the Lutheran Church, depending on the teacher, show respect for religion and religious people and also non religious, we should take it seriously.
In Scandinavia we still call the pastor priest, in Sweden and Norway we have the apostolic succetion, which the Evanglische Kirche find completely absurd.
Sorry you now got to know more than you asked for.
