“I have the nourishment to grow spiritual 'muscles'”

The Eucharist assures me that all is well with myself, i.e. my soul and connection to God. This is what makes me Catholic. It distinguishes me from our separated brethren and non-Christians. I have the nourishment to grow spiritual "muscles" so as to be in good health in this life and the next. 

When I was hospitalized and unconscious for three weeks, I experienced the healing and transformative power of the Eucharist. Upon awakening, I received the Host on the following Sunday and it increased my hope that I would be restored to full health in mind and body. Other virtues were enhanced and an optimism gripped me in my healing process. 

Like food for the body and mind, Holy Communion is the food for eternal life, as Jesus said in the Gospels. The outside world can never have this feeling of immortality and I like that it separates observant Catholics from the rest of human society, which has no clue that it is missing out on the one thing that gives true peace in life. 

Being alone with the Lord, away from the madding crowd, even from fellow congregants. While ours is a communal path to salvation, one should walk alone from time to time with our Lord.
