[1][2] Eppinger's cause for sainthood was opened on 30 August 2005 and she was declared Venerable on 19 December 2011 after Pope Benedict XVI confirmed her life of heroic virtue.

Élisabeth Eppinger was born in France on 9 September 1814 as the eldest of eleven children to poor farmers.

[3] Her parish priest Jean-David Reichard (1796–1867) knew of her desire to establish a religious congregation and aided her in finding companions for her project.

The Bishop of Strasbourg Andreas Raess heard of her from Reichard and met her in July 1848[4] to conduct tests and interviews with her while being convinced of her intentions to serve the ill and the poor.

The cause remained inactive for several decades while a decree from the Congregation for the Causes of Saints on 30 August 2005 resumed the cause and granted "nihil obstat" ('nothing against') to the continuation of the cause while giving her the posthumous title of Servant of God.

The postulation submitted the Positio in two parts in 2009 and in 2010 while historians voted in favor of the cause on 1 December 2009 and consulting theologians did so as well on 29 January 2011; the C.C.S.

She was beatified in Strasbourg Cathedral by Congregation for the Causes of Saints Prefect Cardinal Giovanni Angelo Becciu on 9 September 2018.
