In Roman Catholicism, the Morning Offering is a prayer said by an individual at the start of the day in order to consecrate the day to Jesus Christ. It serves the purpose of preparing the Catholic to focus completely on Christ and give to him all that he or she does during the day. There are several different forms of Offering.
Pope John Paul II said that the Morning Offering is “of fundamental importance in the life of each and every one of the faithful."
The Morning offering is meant to be prayed first thing in the morning, upon waking up. Throughout the day, a Christian offers up everything – joys and successes, difficulties and sacrifices, to Jesus, uniting them to His sufferings and merits so that one’s works gain the merit they can never have apart from Him.
The Morning Offering is suggested to be renewed many times throughout the day with simple short prayers (called "aspirations"), e.g. "I will serve!"; "I offer my work unto you."
A specific Morning offering to the Sacred Heart of Jesus was composed by Fr. François-Xavier Gautrelet in 1844. It reflects the Alliance of the Hearts of Jesus and Mary and is also an Acts of reparation for sins:
- O Jesus, through the Immaculate Heart of Mary,
- I offer you my prayers, works, joys, sufferings of this day,
- in union with the Holy Sacrifice of the Mass throughout the world.
- I offer them for all the intentions of your Sacred Heart;
- the salvation of souls, the reparation for sin, the reunion of all Christians;
- I offer them for the intentions of our bishops and of all members of the Apostleship of Prayer,
- and in particular for those recommended by the Holy Father (i.e., the Pope) this month.
Theological basis and history 
The Catechism of the Catholic Church 2157 states:
- The Christian begins his day, his prayers, and his activities with the Sign of the Cross: "in the name of the Father and of the Son and of the Holy Spirit. Amen." The baptized person dedicates the day to the glory of God and calls on the Savior's grace which lets him act in the Spirit as a child of the Father.
"All that we do without offering it to God is wasted," Saint John Mary Vianney preached. According to Catholic theology, the worth of an action in the eyes of God is found in the intention, i.e. what takes place in the heart of each person, on whether the person lives based on the love for God (the greatest commandment) or love for self. Thus, Catholic spirituality encourages the practice of fixing one's intention towards loving God at the very beginning of the day, through the morning offering. Catholic authors also encourage repeating this offering throughout the day, especially at the start of one's professional work which takes a large part of each day.
The morning offering is an essential part of the theology of sanctification of work, or the use of work, secular or otherwise, as a means of arriving at personal sanctity. The other element in this theology is the actual work done with spirit of excellence in consonance with the intention of offering something "worthy" to the sanctity, majesty and the goodness of the Father God.
This theology is also supported by private revelation to some saints. For example, Sister Josefa Menéndez (1890-1923) reported that she heard Jesus Christ tell her: "When you awake, enter at once into My Heart, and when you are in it, offer My Father all your actions united to the pulsations of My Heart . . . If [a person is] engaged in work of no value in itself, if she bathes it in My Blood or unites it to the work I Myself did during My mortal life, it will greatly profit souls . . . more, perhaps, than if she had preached to the whole world. You will be able to save many souls that way."
Saint Mechtilde (1241-1298), a popular saint during the time of Dante and who was mentioned in his Divine Comedy, also had visions of Jesus Christ and transmitted the following words of Jesus: "When you awake in the morning, let your first act be to salute My Heart, and to offer Me your own . . . Whoever shall breathe a sigh toward Me from the bottom of his heart when he awakes in the morning and shall ask Me to work all his works in him throughout the day, will draw Me to him . . . For never does a man breathe a sigh of longing aspiration toward Me without drawing Me nearer to him than I was before."
It is also said that the morning offering helps "refresh and recharge" the soul, preparing the soul to face each day with the help of God himself.
The morning offering has been an old practice in the Church but it started to spread largely through the Apostleship of Prayer, started by Fr. Francis X. Gautrelet, S.J, and specially through the book written by another Jesuit, Reverend Henry Ramière, S.J., who in 1861, adapted the Apostleship of Prayer for parishes and various Catholic institutions, and made it known by his book "The Apostleship of Prayer", which has been translated into many languages.
