There have been many saints over the centuries who have promoted devotion to the Sacred Heart of Jesus and the Immaculate Heart of Mary. Among them were St. Mechtilde in the 13th century and St. John Eudes in the 17th century.
St. John Eudes in particular did much to promote the devotion, including a revision of the following litany that was written by St. Mechtilde. It is a beautiful litany and invokes both the Sacred Heart of Jesus and the Immaculate Heart of Mary, seeing in them a single, united Heart.

Hail, most loving Heart of Jesus and MaryWe adore you, we praise you, we glorify you, we thank you;
We love you with all our hearts, with all our soul, with all our force;
We offer you our heart, we give it to you, we consecrate it to you, we sacrifice it to you;
Receive it, and possess it entire, purify it, enlighten it, and sanctify it;
In order that in it you may live and reign now and forever. Amen.
