Catholic
The Catholic Church teaches that schism is the rupture of ecclesial communion — the refusal of submission to the Pope or of communion with the Church's members — and wounds the unity Christ willed for his Church. It holds that the Church of Christ subsists in the Catholic Church, while elements of truth exist beyond its visible bounds.
The Orthodox Church understands schism as the breaking of eucharistic communion, most notably the Great Schism of 1054, which it attributes to Rome's unilateral innovations — above all the filioque and claims of papal supremacy. It holds that the Orthodox Church preserves the undivided Church's faith intact.
Lutherans teach that they did not seek schism but reform: the Augsburg Confession was presented as a confession of the catholic faith, and separation came only when Rome condemned the gospel. They hold that true unity is unity in the pure preaching of the gospel and right administration of the sacraments.
The Reformed tradition teaches that separation from a church that has abandoned the marks of a true church — pure preaching, right sacraments, and discipline — is not schism but obedience. It holds that the Reformers left Rome not to divide Christ's body but to preserve the gospel.
Baptists teach that the autonomy of the local congregation under Christ means associations are voluntary, and that separation over doctrine is sometimes faithfulness rather than schism. They hold that true unity is spiritual — shared faith in Christ — not institutional or organizational.
Methodists teach that the Church's unity is a gift of God to be pursued, but that separation may be necessary when conscience and Scripture require it — as in Methodism's own birth from Anglicanism. They hold that schism is tragic, yet faithfulness to the gospel takes precedence over institutional unity.
