(In this thread, I get all bent out of shape by the Catechism declaring what at first glance is contradicted by daily experience.)
According to the Catechism,
 in a certain way, we have already risen with Christ. For, by virtue of the Holy Spirit, Christian life is already now on earth a participation in the death and Resurrection of Christ:
They quote Colossians 2, which appears to use the language symbolically to mean how we turn away from earthly goals (e.g. becoming a billionaire, seeking pleasure) towards heavenly goals (e.g. serving our neighbor, preaching the Gospel). Yet the Catechism appears to interpret this literally by saying “In a certain way,” which to me does not mean symbolically – to speak symbolically means literally we’ve not Resurrected; we’ve simply experienced a change similar to the Resurrection that can be expressed via that symbol.
Should I explain away this apparent literal interpretation as an accident of English Catechism translation?
Yet they continue:
 believers already truly participate in the heavenly life of the risen Christ
citing Colossians 3,
For you have died, and your life is hidden with Christ in God.
What does this mean? I can only guess he means what I’ve already said above regarding ‘death’=conversion, and that St. Paul is implying that the spiritual fruit of our suffering is in the heavenly kingdom. Yet this meaning is something I have been taught that I am “laying on top of” this text – literally he’s not saying anything other than “our lives are hidden in God”. Am I correct in this meaning? Why, again, is the Catechism appearing instead to take this literally, not symbolically? It frustrates me, because not speaking plainly, instead being obscure, is not helping me see a hidden God who lets us suffer in silence.
They also cite Philippians 3:
But our citizenship [colony] is in heaven, and from it we also await a savior, the Lord Jesus Christ.
I still don’t see how these verses support the claim that we are “participating in the heavenly life of the risen Christ”: A heavenly life, by definition, is not an earthly one; it’s claiming we’re involved with what Jesus is doing in heaven! But we are not in heaven: We are here on earth. It is frustrating because if taken literally the Catechism is clearly false, hence a scandal to the uneducated reading it, just like some parts of the Bible. It looks like we’d have to go through mental gymnastics to give it meaning: “Jesus is in heaven, but we’re His Body on earth, and so He’s in heaven working through us as ‘His hands and feet’…” Is that the correct interpretation here? How is even this to be understood? It likewise comes across as absurd, as like someone lying half-off a bed reaching over to work on a laptop sitting on a nearby desk …
The Catechism goes even further, combining the two:
 The Father has already “raised us up with him, and made us sit with him in the heavenly places in Christ Jesus.”
… and this is literally a quotation from Ephesians 2.
I suppose the key here is the idea that humanity is one ‘spiritual organism’, and so either is damned in Adam, or reborn into and hence saved in Christ. (Romans 5) But how can we be one with Christ, as members of His Body, and yet so miserable here on earth while Jesus is in heaven, a place Aquinas says has ‘perfect happiness’? Or how can we be unhappy with Jesus and the Holy Spirit and the Father indwelling within us? (John 14:23, Blessed Miriam Teresa’s Prayer for Beatification) All together this seems another formulation of ‘the mystery of evil’, and this section of the Catechism is remarkably unhelpful.
Of course, struggling with these passages – since the Catechism just quotes them literally and moves on without exegesis – I am reminded of 2 Peter 3:
In [Paul’s letters] there are some things hard to understand that the ignorant and unstable distort to their own destruction, just as they do the other scriptures.
I suppose I am unstable, and I pray frequently for more faith and wisdom, yet I’m continually frustrated and unhappy by how distant God is.
