As this is a duplicate thread, I'll offer a duplication of my initial response;
Perhaps, when all the individual bells and whistles (superficial 'sweets' for the neophytes) are removed, the 'true Xtian, is no different in 'quality' then the 'true' Hindu or any religion's deeper practitioners.
The mystics, those who delve beyond the superficialities, from all paths converge in 'understanding/experience'.
The one quality of all mystics of any path is understanding/experiencing the 'oneness' of all, and humility, lack of ego/Pride.
Those who would argue for the 'distinction' of Xtianity, or any other 'path', is deep in the blindness and the 'sin' of pride, vanity.
All paths decry pride/ego vanity, yet the neophytes seem to laud it as if it were some kind of 'virtue'. Quite the opposite, but we must start from where we stand.
So a 'true Xtian' is humble, yet never sees himself as such; entertains no vain fantasy of 'free-will' and 'choice' (autonomy from their god (as 'god of our own world), and the universe perceived).
A person displaying these characteristics will be recognized on any path, any discipline, as a brother by anyone past the initial 'stage' of neophyte (beyond which, most never progress).
