That is the assertion and since the “the Church” cannot be in error anything I read must either be in agreement with Church dogma or be heresy.
One redundant and the other worse than useless. So what exactly is it that I am to read?
The Baltimore Catechism is too simple and the latest Catholic Catechism is subject to your interpretation so what’s left for me to read?
Read Baltimore if you can’t figure out the new one. Also, ask someone Catholic when in doubt.
