This is where I disagree with a some other Catholics. For me the Person and Work of Christ (Christology) Is the absolute beginning point of understanding the Church it is ‘The Truth’ upon which all else is. From there as your starting point you can expand and talk about sin and therefore the need for the Sacrifice of Jesus and then explain about the Eucharist etc.
There are many moral people who do not believe in Christ or the Church.
I don’t think we disagree. All things with Christ start with love and compassion.
As you said, from there it moves on to other things.
This series will continue and along the way some of that will be discussed.
