“Love does not stay idle.” – St. Catherine of Siena, Letter T82

Can we really imitate a fourteenth century saint whose life had such great austerity, who fasted with such severity? What lesson can we learn from a Church Doctor whose diet was raw vegetables, whose sleep pattern was non-existent, and whose community was called the “Sisters of Penance”?

Admittedly St. Catherine of Siena’s life was one of penance. Bl. Raymund of Capua’s biography of her makes this clear enough. But I think it’s hard to make sense of St. Catherine’s life of penance unless you’ve made sense of her life of love. Here are a few short teachings from St. Catherine on love:

Love impels us to desire. If love is the reason why we desire, then love is the reason why we live. We can’t live without love because we always want to love something. Love moves us and unites us to the thing we love in order to rest in it. When we love something we don’t just want a superficial understanding of it, but we want what it really is, and nothing keeps us away from it.

St. Catherine knew how to fast because she knew how to love. Penance was admittedly part of her life and letters, but her literature is saturated with descriptions of love. It’s perhaps the single most common word in her letters. There are many goods in this life that we desire, but the supreme good – God, who gives us divine life, beatitude, ultimate happiness – this is the ultimate end that we strive to have in love. St. Catherine knew her need for love.She often ended her letters with the salutation “Love, love, love one another, sweet Jesus, Jesus, Love.”

Love makes room. In love we forget about ourselves and make room for another. When we fast from little goods we make room for perfect love that comes from Love himself. In doing this we can see where we have false loves – when we love ourselves or another in a way that doesn’t reflect reality. Removing a false self-love in us, God makes room within us for himself. But us loving God more means we become more of ourselves; there is more of us present in each act of love. God makes room in the temple of ourselves until he lead us to the incorruptible temple of himself.

Only in receiving this divine love could St. Catherine care for the sick and the poor and nurse plague victims the way she did. Love, not penance, was the foundation of her life:

“If, then, we made ourselves build on penance as a foundation, it might come to nothing and be so imperfect that we would seem to be deprived of God, and soon [we] would fall into weariness and bitterness…we should strive to give only a finished work to God who is Infinite Love who demands from us only infinite desire.”  – Letter to Daniella of Orvieto

This divine love was the source of her own love towards those she cared for:

“God has loved us without being loved, but we love him because we are loved…we cannot profit him, nor love him with this first love…In what way can we do this, then, since he demands it and we cannot give it to him? I tell you…we can be useful, not to him, which is impossible, but to our neighbor…love is gained in love by raising the eye of our mind to behold how much we are loved by God. Seeing ourselves loved, we cannot otherwise than love.”  – Letter to Brother Bartolomeo Dominici

Love transforms. St. Catherine states that “love transforms one into what one loves” (Dialogue 60). In loving God, we become like the one we love. When two things are joined together, there can’t be anything between them, otherwise there wouldn’t be a complete union of them together. This is how God wants us to be with him in love. Once we are removed from selfish love we can love God with the love with which  he has first loved us. St. Catherine takes this transformative love to the highest level:

“The eternal Father said [to me], ‘If you should ask me what this soul is, I would say: she is another me, made so by the union of love.” (Dialogue 96)

By God’s love we become kneaded and knit into our Creator who redeems us and lets us participate in his divine love.

Ultimately, St. Catherine’s love led her to a life of penance and service to her neighbor. There’s no saying it wasn’t a harsh life – she died at age 33 – but it was certainly a life lived in love.  She saw all of her actions and penances tied up in the cross of Christ: a tree not of unnecessary torture and grief but a tree of love. St. Catherine wished to graft herself into that tree and so be joined to the fiery love that comes from Christ.

St. Catherine certainly had her share of penance, but I think the primary lessons she teaches us are in love. If you want a reason for St. Catherine’s penitential life, look to Christ who loved her with an infinite love. Cling to Christ as the one who lives and who wants to live in you.
