Atheistically
Which Christianity? Gnosticism?
Im not that sharp on this topic but here goes.
Gnosticism had roots before Christianity, it also evolved and compiled into different sects within early Christianity.
Its better to look at each individually, more so then comparing.
Gnosticism was for the most part short lived. The rise of Christianity was for the mnost part always on a scale upwards in numbers, with certain areas growing faster then others.
Also take into to note Christianity was very wide and diverse for the first few hundred years, as Judaism was wide and diverse before the temple fell.
