The Solemnity of the Most Sacred Heart of Jesus
is today. There is information on it here.
"May Thy Heart dwell always in our hearts!
May Thy Blood ever flow in the veins of our souls!
O Sun of our hearts, Thou givest life to all things by the rays of Thy goodness!
I will not go until Thy Heart has strengthened me, O Lord Jesus!
May the Heart of Jesus be the King of my heart!
Blessed be God. Amen."
- St. Francis deSales, Bishop and Doctor of the Church
"Relatively modern under the form that it actually bears, the devotion to the Sacred Heart has its dogmatic roots in the deposit of faith. It was contained in germ in the words of St. John: 'The Word was made Flesh, and dwelt among us ... having loved His own ... He loved them unto the end' (Jn 1:14; 13:1). What, in fact, is the Incarnation? It is the manifestation of God, it is God revealing Himself to us through the Humanity of Jesus: Nova mentis nostrae oculis lux tuae claritatis infulsit
(Preface of the Nativity); it is the manifestation of Divine love to the world: 'God so loved the world, as to give His Only-begotten Son'; and this Son Himself so loved men as to deliver Himself up for them: 'Greater love than this no man hath, that a man lay down his life for his friends': Majorem hac dilectionem nemo habet
(Jn 15:13). All the devotion to the Sacred Heart is in germ in these words of Jesus. And in order to show that His love had attained the supreme degree, Christ Jesus willed that immediately after He had drawn His last breath on the Cross, His Heart should be pierced by the soldier's lance." - Blessed Columba Marmion, O.S.B.
"O Sacred Heart of Jesus, I adore Thee in the oneness of the Personality of the Second Person of the Holy Trinity. Whatever belongs to the Person of Jesus, belongs therefore to God, and is to be worshipped with that one and the same worship which we pay to Jesus. He did not take on Him His human nature, as something distinct and separate from Himself, but as simply, absolutely, eternally His, so as to be included by us in the very thought of Him. I worship Thee, O Heart of Jesus, as being Jesus Himself, as being that Eternal Word in human nature which He took wholly and lives in wholly, and therefore in Thee. Thou art the Heart of the Most High made man. In worshipping Thee, I worship my Incarnate God, Emmanuel. I worship Thee, as bearing a part in that Passion which is my life, for Thou didst burst and break, through agony, in the garden of Gethsemani, and Thy precious contents trickled out, through the veins and pores of the skin, upon the earth. And again, Thou hadst been drained all but dry upon the Cross; and then, after death, Thou wast pierced by the lance, and gavest out the small remains of that inestimable treasure, which is our redemption.
2. My God, my Saviour, I adore Thy Sacred Heart, for that heart is the seat and source of all Thy tenderest human affections for us sinners. It is the instrument and organ of Thy love. It did beat for us. It yearned over us. It ached for us, and for our salvation. It was on fire through zeal, that the glory of God might be manifested in and by us. It is the channel through which has come to us all Thy overflowing human affection, all Thy Divine Charity towards us. All Thy incomprehensible compassion for us, as God and Man, as our Creator and our Redeemer and Judge, has come to us, and comes, in one inseparably mingled stream, through that Sacred Heart. O most Sacred symbol and Sacrament of Love, divine and human, in its fulness, Thou didst save me by Thy divine strength, and Thy human affection, and then at length by that wonder-working blood, wherewith Thou didst overflow.
3. O most Sacred, most loving Heart of Jesus, Thou art concealed in the Holy Eucharist, and Thou beatest for us still. Now as then Thou savest, Desiderio desideravi
-'With desire I have desired.' I worship Thee then with all my best love and awe, with my fervent affection, with my most subdued, most resolved will. O my God, when Thou dost condescend to suffer me to receive Thee, to eat and drink Thee, and Thou for a while takest up Thy abode within me, O make my heart beat with Thy Heart. Purify it of all that is earthly, all that is proud and sensual, all that is hard and cruel, of all perversity, of all disorder, of all deadness. So fill it with Thee, that neither the events of the day nor the circumstances of the time may have power to ruffle it, but that in Thy love and Thy fear it may have peace."- Venerable John Henry Newman, C.O.
There was also a sermon of the Venerable, of which the following notes survive:
The Sacred Heart
"1. INTROD.—Many devotions in Holy Church. This is one which has spread of late years, more, I may say, than any other. Today is the special feast of it; and [this] leads me to explain in what it consists.
2. Our Lord is One. He is the one God. He took on Him a manhood, a body and soul; that body from Mary. Still, He was one, not two—one, as each of us is one.
3. We too, in our way, are each of us one, though we are two—soul and body—and the body has parts; [nevertheless] each of us is one
. This is what is meant by speaking of our Lord's [oneness] as we speak of our own.
4. And though each of us is thus composite, we can love each other as one, though of so many parts. And in like manner, though our Lord is God and man, with a soul [and body], we can contemplate Him as one, and worship, love Him as one.
5. Further, if I said I loved the face, or the smile, or liked to take the hand of my father or mother, it would be because I loved them. And so, when I speak of the separate portions of our Lord's human frame, I really am worshipping Him. So in the Blessed Sacrament we do not conceive of His Body and Blood as separate from Him.
6. Devotions at various times [and ages]—the Wounds, the Blood, the Face—and in like manner the Heart. We worship [each] as Him, as that One Person who is God and man; we worship [Him
] by the memento, the pledge of His Heart.
7. Why? The Heart a symbol
—so the Wounds and the Blood. [In contrast with these] a symbol is sometimes that which [only] expresses and reminds—thus water, oil, wine, bread.
8. What is the Heart the symbol of?—of His love, His affection for us, so that He suffered for us—the agony in the garden.
9. Moreover, of His love in the Holy Eucharist.
10. The Heart was the seat, first, of His love for us; secondly, of His many griefs and sorrows.
[The following were appended, apparently as alternatives:]
7. Of two things especially to remind us now, when the world is so strong—His power and His love. He will overcome by love.
8. The Heart is the emblem of His love—in worshipping It we worship Him."
