would the part 'he descended into hell' refer to drinking the cup of the wrath of the Father. Because He was smitten and bruised and the Father was pleased to do this. Jesus had prayed for this cup of the wrath of the Father to pass Him.
But, then Jesus submitted to the Fathers will.
so, when Jesus felt the full force of the Fathers rejection and wrath, was not this the hell He was plunged into?
Am I wrong?

BTW. Worldview has a really easy to use Catechism by Brandon Howse.
It has scripture references and is easy to use. Small book, with large type for young eyes.
But, later I would definitely use the Shorter Catechism.
I like Training Hearts Teaching Minds. Can't remember the author atm.

Jude 3
...contend earnestly for the faith which was once for all handed down to the saints.
