Saint Bonaventure (1221-1274) the Seraphic Doctor of the Catholic Church explains that reading Sacred Scripture is not enough. One can only properly understand the Scriptures if he already has the truth Faith. Bonaventure explains that the Scriptures are gift for the ultimate purpose of leading us to Heaven. Thus if we do not already know and love Christ, then the Scriptures are in vain. The Scriptures are a guide if only we know the destination, which is eternal beatitude with the Holy Trinity and all the Saints.
From all this it follows that it is impossible for anyone to start to recognize Scripture for what it is if he does not already have faith in Christ infused into him. Christ is the lamp that illuminates the whole of Scripture: he is its gateway and its foundation. For this faith is behind all the supernatural enlightenments that we receive while we are still separated from the Lord and on our pilgrimage. It makes our foundation firm, it directs the light of the lamp, it leads us in through the gateway. It is the standard against which the wisdom that God has given us should be measured, so that no-one should exaggerate his real importance, but everyone must judge himself soberly by the standard of the faith God has given him.
The substance and fruit of holy Scripture is very specific: the fullness of eternal happiness. For this is what Scripture is – its words are words of eternal life, and it is written not just so that we should believe, but specially so that we should possess eternal life in which we may see, and love, and have all our desires fulfilled. When they are fulfilled, then we shall know the superabundant love that comes from knowledge, and so we shall be filled with all the fullness of God. God’s Scripture tries to lead us to this fullness, and to the truth of the preaching of the apostles. It is to this end, with this intention, that we should study holy Scripture, and teach it, and hear it.
If we are to follow the direct path of Scripture and come straight to the final destination, then right from the beginning – when simple faith starts to draw us towards the light of the Father – our hearts should kneel down and ask the Father to give us, through his Son and the Holy Spirit, true knowledge of Jesus and of his love. Once we know him and love him like this, we shall be made firm in faith and deeply rooted in love, and we can know the breadth, length, depth and height of holy Scripture. That news can then lead us to the full knowledge and overwhelming love of the most holy Trinity. The desires of the saints draw them towards the Trinity, in which all that is good and true is and finds its completion.
