Devotion to the Sacred Heart of Jesus is the Eucharist. The Eucharist is often referred to as the Real Presence. This is because Christ in His fullness abides in the Eucharist. In it dwells both His human and divine natures. The Catechism of the Catholic Church in paragraph 1374 explains this presence:
“The mode of Christ’s presence under the Eucharistic species is unique. It raises the Eucharist above all the sacraments as “the perfection of the spiritual life and the end to which all the sacraments tend.” In the most blessed sacrament of the Eucharist “the body and blood, together with the soul and divinity, of our Lord Jesus Christ and, therefore, the whole Christ is truly, really, and substantially contained.” “This presence is called ‘real’ – by which is not intended to exclude the other types of presence as if they could not be ‘real’ too, but because it is presence in the fullest sense: that is to say, it is a substantial presence by which Christ, God and man, makes himself wholly and entirely present.”
St. Teresa of Jesus was devoted to the Blessed Sacrament and this especially shows through in her teachings on the Sacred Humanity of Christ. She exhorted her nuns to meditate on the life of Christ and even wrote that to abandon the humanity of Jesus was a hindrance to prayer. She teaches this because God chose to reach out to His people through the human person. Consequently devotion to the Sacred Heart of Jesus encourages Carmelites to reflect on the humanity of Jesus who loves with a human heart.
So after Christ rose from the dead and ascended into heaven to sit at the right hand of the Father, He did not leave earth. Jesus is present in the Blessed Sacrament in the same way that He is present in Heaven. Therefore His physical heart is there in the Blessed Sacrament.
All this then makes one see why St. Teresa would write, “Certainly, I think that if we were to approach the most Blessed Sacrament with great faith and love, once would be enough to leave us rich. How much richer from approaching so many times as we do. The trouble is we do so out of routine, and it shows.” [Meditations on Song of Songs, 3:13]
It shows. We do see the bread and wine and behind them we believe that Christ is present, since faith supplies what the senses fail to perceive. But how routine has our reception of the Blessed Sacrament become? The Sacrament does confer grace; how could one be in the Presence of Christ and not be affected? The grace received is the grace to love. Through our faith in the Eucharist, charity grows in us both towards God and others. Does it show?
St. Teresa gives advice on how to receive the Eucharist with greater devotion and profit: “After having received the Lord, since you have the Person Himself present, strive to close the eyes of the body and open those to the soul and look into your own heart… You should acquire the habit of doing this every time you receive Communion.” [Way of Perfection, 34:12] And “ If you immediately turn your thoughts to other things, if you pay no attention and take no account of the fact that He is within you, how will He be able to reveal Himself to you? This, then, is a good time for our Master to teach us, and for us to listen to Him. [Way of Perfection, 34: 10]
She also wrote that, “From certain things He told me, I understood that after he ascended to heaven He never came down to earth to commune with anyone except in the most Blessed Sacrament.” [Spiritual Testimonies, 13] Therefore it is important to receive the Eucharist in a state of grace. To this she also wrote that, “I understood well how much more priests are obliged to be good than are others, how deplorable a thing it is to receive this most Blessed Sacrament unworthily.” [Life, 38: 23]
Our devotion to the Eucharist and the Sacred Heart of Jesus can be also fostered in Adoration of the Blessed Sacrament, whether exposed or reserved in the tabernacle. This is a great way to strengthen our faith and to draw closer in our union with Christ. Many communities, especially religious communities, have Eucharistic Exposition and Adoration available for the faithful. Prayer before the Blessed Sacrament is a great way to foster holiness. St. Teresa made certain that the Blessed Sacrament was in each of her foundations. This was often the first task that she attended to when making new foundations as she writes in her Foundations chapter 29, “We took the Blessed Sacrament and had it reserved in the church with great and well-organized solemnity. It caused much devotion.”
Since we have such a blessing in the Real Presence let us, “Behold Him here without suffering, full of glory, before ascending into heaven, strengthening some, encouraging others, our companion in the most Blessed Sacrament; it doesn’t seem it was in His power to leave us for even a moment.” [Life, 22: 6]
