Christianity is uniquely confused and plagued with disinformation. The realm of secular humanism is almost worse, but your basic option in a secular time. There is no reason why secular humanism has to be so braindead. And there is no reason for such people to dismiss all spiritual beliefs as superstitions. Such people have rarely studied Kant and can’t see their own metaphysics and superstition. They find Nietzche groovy and degenerate into pseudo-philosophers. The issues of soul are a case in point. There is much superstition there, but the core meme is an aspect of human psychology and can’t be amputated. Spiritual beliefs are in the materialism of Samkhya equally material and many students of yoga claim to be doing a spiritual study, but yoga invokes Samkhya at the start and is thus not technically a ‘spiritual subject’.
The history of Christianity can help as a ‘religious’ exercise to see the way the whole subject degenerated, turning ideological and political and serves no purpose beyond crowd control by politicians.
I think our comments on abortion and soul are on the mark although there are still many obscure points here. But the theological injunction against abortion by the theologians has totally misled the public. Such people are not spokesmen for god, but hopless idiots in a tradition so corrupted as to be a dead loss. The reproductive process is an aspect of nature which all too often spawns unlimited or exponential life processes. We must bring human reason to bear to see that women cannot be regulated in the manner of theological now rightist/fascist politics.
I have revised this at some points as indicated as notes in a further update… Update: this account here can I hope help to orient thinking on abortion and soul questions, but it is still some…
