[2] In a 2012 schism, Bishop Mark Lawrence and the majority of the leaders and parishes of the historical Diocese of South Carolina departed from the Episcopal Church.

[4] On September 19, 2019, a federal court awarded the names and intellectual property to the Episcopal Church and its South Carolina diocese.

The Bishops Disciplinary Board cited three specific actions by Lawrence which, it stated, showed his abandonment of his ordination vows.

Second, a set of 2011 amendments to the South Carolina nonprofit corporate charter of the diocese, filed by Lawrence, "deleting all references to the [Episcopal] Church and obedience to its Constitution and canons."

Third, in November 2011, the issuance of quitclaim deeds for the real estate of every diocesan parish, in violation of the Church's Dennis Canon.

[10] According to the Reverend Jim Lewis, the canon to the ordinary for the Diocese of South Carolina, the dispute was over Schori's increasing acceptance of relativism in the church.

"[15] She further wrote that the South Carolina diocese "continues to be a constituent part of The Episcopal Church, even if a number of its leaders have departed.

[3] On February 3, 2015, a South Carolina Circuit Court judge ruled that the breakaway diocese was entitled to the property and the historical name.

The court split on the issue of who owned the name Diocese of South Carolina, leaving that portion of the 2015 decision in place.

In his clarification of the multiple Supreme Court opinions, Dickson explained, "the Dennis Canon by itself does not create a legally cognizable trust, nor does it transfer title to property".

[18] A Federal court ruled on September 19, 2019, that the name and marks belong to the Episcopal Church and its South Carolina diocese.

Woodliff-Stanley and ADOSC Bishop Chip Edgar, who had been consecrated in 2022, began mediation to discuss a resolution to the disputes between the dioceses in spring 2022.

As part of the settlement, St. Christopher Camp and Conference Center on Seabrook Island was transferred from the ADOSC to the EDOSC on October 1, 2022.

"While each diocese has had to leave things on the table to get to this moment, and while we experience pain over losses of some of the historic churches our members hold dear, even still, we have seen the Spirit at work in drawing us toward God’s redemptive way of love at every juncture.”[22] The Cathedral of St. Luke and St. Paul affiliated with the departing diocese in the schism, leaving the continuing Episcopal Church in South Carolina without a cathedral.

[23] Episcopal Church Presiding Bishop Michael Curry visited the diocese in April 2016, and preached during a service at the new cathedral.
