As discussed in previous posts, the Roman Catholic Church on May 23, 2015, beatified Archbishop Oscar Romero after it had determined that he was a martyr, who is someone who was killed because of hatred of his Christian faith and, therefore, who did not have to have committed a miracle for this honor. Such beatification is a necessary, but not sufficient, condition for someone to become a saint of the Church.
On March 6, 2018, Pope Francis authorized the Church’s Congregation for the Causes of Saints to promulgate a decree concerning “the miracle, attributed to the intercession of Blessed Oscar Arnulfo Romero Galdámez, archbishop of San Salvador.” That miracle was the healing of a Salvadoran pregnant woman who was suffering from life-threatening complications, but who was healed after she had prayed for Romero’s intercession. 
This papal decree followed the October 2017 unanimous decision by a Vatican panel of medical experts that there was no scientific explanation for the woman’s recovery; the December 2017 approval of that decision by a panel of theologians; and the February 2018 approval of that decision by the Congregation for the Causes of Saints.
The Congregation for the Causes of Saints is the congregation of the Roman Curia that oversees the complex process that leads to the canonization of saints, passing through the steps of a declaration of “heroic virtues” and beatification. After preparing a case, including the approval of miracles, the case is presented to the Pope, who decides whether or not to proceed with beatification or canonization.
In 2016, Cardinal Parolin, under the mandate of Pope Francis, approved the current Regulations for the Medical Board of the Congregation for the Causes of Saints that introduced the necessity of a qualified majority of at least at least 5/7 or 4/6; to proceed to the examination of a presumed miracle. These new rules approved by Pope Francis are designed to make the process for approving a miracle in a sainthood cause more stringent.
We now await announcement of the time and place of the canonization.
As someone who strives to be a Christian of the Presbyterian persuasion and who already has self-designated Romero as his personal saint because of his courage in proclaiming the Gospel in El Salvador and denouncing its government’s violations of human rights, I am grateful for the Roman Catholic Church’s making Romero’s sainthood official.
