Considered to be a "second founder" of the Franciscans, he was an outstanding teacher, and a spell-binding preacher. He was known for his virtue and wisdom. He is known as the "Seraphic Teacher" because of his deeply mystical understanding of the Faith.
O Lord God, who art the light of the minds that know thee, the life of the souls that love thee, and the strength of the hearts that serve thee: Help us, following the example of thy servant St. Bonaventure, so to know thee that we may truly love thee, and so to love thee that we may fully serve thee, whom to serve is perfect freedom; through Jesus Christ our Lord, who liveth and reigneth with thee and the Holy Spirit, one God, now and for ever. Amen.
Prayer of St. Bonaventure.
Pierce, O most sweet Lord Jesus, my inmost soul with the most joyous and healthful wound of Thy love, and with true, calm and most holy apostolic charity, that my soul may ever languish and melt with entire love and longing for Thee, may yearn for Thee and for thy courts, may long to be dissolved and to be with Thee.
Grant that my soul may hunger after Thee, the Bread of Angels, the refreshment of holy souls, our daily and super substantial bread, having all sweetness and savor and every delightful taste.
May my heart ever hunger after and feed upon Thee, Whom the angels desire to look upon, and may my inmost soul be filled with the sweetness of Thy savor; may it ever thirst for Thee, the fountain of life, the fountain of wisdom and knowledge, the fountain of eternal light, the torrent of pleasure, the fullness of the house of God; may it ever compass Thee, seek Thee, find Thee, run to Thee, come up to Thee, meditate on Thee, speak of Thee, and do all for the praise and glory of Thy name, with humility and discretion, with love and delight, with ease and affection, with perseverance to the end; and be Thou alone ever my hope, my entire confidence, my riches, my delight, my pleasure, my joy, my rest and tranquility, my peace, my sweetness, my food, my refreshment, my refuge, my help, my wisdom, my portion, my possession, my treasure; in Whom may my mind and my heart be ever fixed and firm and rooted immovably. Amen.
