The Effects of Holy Communion

What are the chief effects of a worthy Holy Communion?

  1. An increase of sanctifying grace;
  2. Preservation from mortal sin, and remission of venial sin;
  3. The lessening of our inclinations to sin and the help to practice good works.

So sharpen your spiritual sword, O Knight of Christ, by allowing your Eucharistic Lord to transform you. Receive Him worthily.

Why a Worthy Reception Matters

Holy Communion is not merely a symbol or a private devotion. In the Eucharist, Catholics receive Jesus Christ truly present—Body, Blood, Soul, and Divinity. The Catechism of the Catholic Church explains that fruitful reception deepens our union with Christ, strengthens charity, separates us from sin, unites us more closely with the Church, and commits us to care for the poor (CCC 1391–1397).

A “worthy” reception does not mean that a person must be spiritually perfect. It means approaching the sacrament in faith, with reverence, and in a state of grace. A Catholic who is conscious of having committed mortal sin should receive sacramental absolution before receiving Holy Communion.

How to Prepare for Holy Communion

Prepare by participating attentively in Mass, observing the Eucharistic fast, and asking God for a humble and recollected heart. If needed, make a careful examination of conscience and receive the sacrament of confession.

After Receiving Holy Communion

Remain in quiet thanksgiving after Communion. Adore Jesus, thank Him for His presence, offer Him your needs and the needs of others, and ask for the grace to live what you have received. The fruits of Holy Communion are meant to continue beyond Mass in prayer, charity, and faithful daily service.
