Oil dedicated to The Immaculate Heart of Mary on prayer cloth
Devotion to The Immaculate Heart of Mary grew up in parallel. But at a lesser intensity than that of devotion to the Heart of Jesus. Only starting to become more prominent during the time of St John Eudes.
St. John brought people to love Christ and the Virgin Mary by speaking tirelessly about their Hearts. The sign of the love God shows for us and the communion to which we are called.
The main difference between the devotions to the hearts of Jesus and Mary is that the one concerned with Jesus emphasizes his divine heart as being full of love for mankind. But with this love, for the most part, being ignored or rejected. While devotion to Mary’s heart is essentially concerned with the love that her heart has for Jesus, for God.
Therefore, it is not an end in itself so the love of her heart is meant to be a model for the way we should love God. The fact that her heart is immaculate, that is sinless. This means that she is the only fully human person who is able to really love God in the way that he should be loved.
Honoring Mary’s Immaculate Heart is really just another way of honoring Mary as the person. Who was chosen to be the Mother of God? Recognizing her extraordinary holiness and the immense love she bestowed on Jesus as his mother. The person who was called to share in and co-operate in his redemptive sufferings.
