I understand that's their stance, but to me (& I suspect other pragmatic people) the notion doesn't sit well.
How could something so complex & perfect have simply have always of existed? How could God have arisen from nothing?
The point is that God didn't arise from nothing. God exists outside of the realm of Human Understanding in a Material Universe...there was no 'before' God, God didn't arise at all, least of all from 'Nothing' god simply Is...God created not only the Universe, but Time itself. So any supposition on what existed before God is irrelevant to what they believe and is a measure of our own limitations rather than that of God.
That is why the notion of Nothing--->God--->Universe doesn't have an logical consistency.
It seems that stance is taken as yet another handy means of side stepping difficult questions...
I disagree, as the stance is a very difficult position to hold due to our own perception being dependent upon linear time. It asks more difficult questions than it answers.
There are religions, including those related to Christianity such as Mormonism that have a different view, for example they believe that God was once a mortal who progressed to Godhood. So then the question would have some relevance...but the way in which you phrased your position is not, as it assumes God was created and is limited by linear time as are we. It essentially assumes a framework that doesn't apply to the subject therefore is not logically sound.
Sounds like just defining your way out of a difficult question.
It's the opposite, as that definition has more difficulty being conveyed than others, like the example given with the LDS Church...
That the explanation is essentially beyond our own limitations due to our reliance on a perception defined by linear time doesn't mean that it isn't coherent or designed to avoid such questions...it answers such questions...
What existed before the Universe? --->God
What existed before God? ---> [we have not the ability to answer that question within a framework due to the limitations of our innate perception]...God simply exists.
If you are a follower of Startrek TNG, you may remember an episode where the Enterprise is forced beyond Warp 9.9....the extra-relativistic speeds meant that the Enterprise then occupied all points, at all times within the Universe simultaneously...think of God as doing the same thing, but with the addendum of also being extant outwith the Universe where there is no limitations defined by Space-Time.
I find it illogical to see how God appeared out of nothing, or has always existed, especially when there is not a single shred of evidence to suggest this to be the case? Surely at some point there was nothing in some sense of the word?
As above really...you are attempting to understand a position through your own adherence to a linear time framework. You assume that there must be a beginning (and by association an end) to all things, yet God is defined as having neither Beginning nor End, he is inherently both as regards the Universe itself as he created it (as in Revelation 22:13), but God is not beholden to that linear framework...God created that framework within the Universe, God isn't subject to it.
