“Of Mustard and Mulberries”: A Sermon for the Seventeenth Sunday after Pentecost 2025
A sermon preached at St. Mark’s Episcopal Church in St. Alban’s, West Virginia on the Seventeenth Sunday after Pentecost
Focus Text: Luke 17:5-10 (specifically vv. 5-6)
Just before this passage, Jesus is instructing his apostles on sin, faith, and duty. Particularly important is what Jesus says about offering forgiveness to those who repent of their sin against you: as many as seven times in a day if they sin against you and repent seven times in a day (don’t take the number in a woodenly literal sense - forgive as many times as someone repents).
It is in response to this that the apostles cry out to Jesus, “Increase our faith!” Jesus’ response? Mustard seeds and mulberry bushes… WHAT?!
We need to always remember the sever ways of reading scripture. Here it is crucial to read the text in the allegorical sense — a spiritual way of reading focused on symbolic connections — and also the anagogical sense — spiritual or mystic reading of scripture.
The Church Fathers help us to better understand the symbolic meaning of the mustard seeds and mulberry tree in a way that may surprise us. This sermon draws on sermons and commentaries by St. Augustine of Hippo, St. John Chrysostom, St. Cyril of Alexandria, and even rabbinic Jewish tradition to understand the symbolic meaning of these plants — what it means to have mustard seed faith and the meaning of uprooting a mulberry tree and planting it into the sea. This helps us to better understand how Jesus is responding to the apostles’ cry to increase their faith.
A little faith is all it takes to do incredible things, even uproot the mulberry trees (the temptations of the devil, the passions, vices, and habitual sins) and cast them into the abyss. And when we cry to God for help in faith, God will always increase our faith. Grace always precedes and follows us as we walk in faith as disciples of Jesus Christ. Divine Grace makes it possible for us to do what we cannot do on our own — but for God all things are possible. God adds to our faith when we cry out for strength, for aid, for faith. This helps us to do the impossible, even to forgive those we wish not to forgive; to root out evil from within us; to face our fears; to heal from grief; to face terminal illness with dignity, grace, and unwavering faith; to release control and trust in the Lord.
Cry out to God to increase your faith. He’ll do it every time.
