What is Lent?

During Lent, our focus is on the Kingdom coming, not on the Kingdom having come. The readings in the Masses for Lent and in the Liturgy of the Hours focus heavily on the spiritual journey of Old Testament Israel toward the coming of Christ, and the salvation of mankind in His death and resurrection.
We, too, are on a spiritual journey, toward the Second Coming and our future life in Heaven. In order to emphasize that journey, the Church, during Lent, removes the Alleluia from the Mass. We no longer sing with the choirs of angels; instead, we acknowledge our sins and practice repentance so that one day we may again have the privilege of worshiping God as the angels do.(Culled from Catholicism).

What does the The Immaculate Heart mean?

The Sacred Heart of Jesus is often shown encircled with thorns, with flames coming out of the top, rays flowing from all around it, and a cross at the peak of the flames.  In it, we see Jesus’ love for us represented in the heart, and the pain He endured in the thorns.  His love is so powerful, so all-encompassing, that it comes out from His heart in rays.  We must not forget the cross — the suffering, of course, but also the victory — as the pinnacle of our faith.(Culled from SnoringScholar)

The Unity of the Faith

Why is the Church divided? Because of Satan. Let us all true believers of Jesus Christ avoid this.
The Scripture says "Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ..." Eph. 4:13
