@Thomas .. mmm .. I see where you are coming from.
Thank you.
You are saying that immortal could mean in the sense that a soul is spiritual and does not necessarily mean that it exists forever after death.
In Hebrew theology there are hierarchical 'gradations' of the soul, designated by different terms –
nefesh,
ruah,
neshamah. In the Kabbalah we have
hayah and
yedidah. There are corresponding terms in Latin and Greek in Christian speculative theology, and no doubt in Islam, too.
The lowest level,
nefesh (Gk:
psyche, Lt:
animus) are, according to Scripture, not immortal, but dies with the death of the body.
The idea of 'being born again' in baptism is the activation of the higher aspects of the soul, but the immanent presence of the Holy Spirit. Then, and only then, do we start seriously talking about immortality.
Life, however, in its basic sense, goes on. It's just that that life as such is neither yours nor mine, d'you see? Life goes on, even though I do not, my forbears have gone, future generations have yet to be, but life endures ...
... It all gets rather deep, metaphysical, speculative ...
The Catechism is addressing Catholics, so certain matters are given. One is 'pastoral necessity' in how the doctrine is presented.
