Augustine on Schism

http://www.anglican-mainstream.net/index.php/2007/11/06/augustine-on-schism/

[Anglican Mainstream] 6 Nov 2007--Augustine’s account of schism:‘By false doctrines concerning God heretics wound faith, by iniquitous dissensions schismatics deviate from fraternal charity, although they believe what we believe’ (De fide et symbolo, ix).

That is, when people do not believe the same things, then it is not schism. Schismatics “deviate from fraternal charity” though sharing the same beliefs.
