The body and blood of our Lord and Saviour Jesus Christ is not only a sacrament of the Church. The celebration of the body and blood of Christ in the Eucharist is a pure, perfect and living sacrifice. The Eucharist is the sacrifice of the cross where Christ´s body was immolated, and his blood was poured out for us.
In a nutshell, the passion and death of Jesus Christ is an exemplification of courage versus cowardice on the part of all the actors involved. From Christ himself to the least participant in the passion and death narrative. In Christ, we see a journey of courage from the inception of his public ministry till his death on the cross.
The spirit of Lent is one of sacrifice. A sacrifice that leads to transformation and renewal. A sacrifice of Lent is the Easter joy of the resurrection. Hence, Lent invites us to renounce something precious in us: ego, desire or things. It is a time of penitential sacrifice to give up something we hold dear for the sake of the gospel.
The leprosy of sin is more contagious than physical leprosy as a disease. This is because like leprosy, sin separate and ostracize us from God and the Christian community. Good enough, though leprosy has no remedy. For sin, there is repentance and the infinite mercy of God.
