The other religions look toward man; their effort is directed to the heart and conscience with the purpose of transforming them. Sacrifice disappears, or rather it changes from the exterior to the interior. God is conceived of as a father, always ready to welcome him who comes to him. Conversion, perfection, sanctification become the pre-eminent religious acts. Worship and prayer cease to be incantations and become reflection, meditation, virile effort; while in religions of the first class the clergy have an essential part, as intermediaries between heaven and earth, in those of the second they have none, each conscience entering into direct relations with God. It was reserved to the prophets of Israel to formulate, with a precision before unknown, the starting-point of spiritual worship. Bring no more vain offerings; I have a horror of incense, Your new moons, your Sabbaths, and your assemblies; When you multiply prayers I will not hearken. Your hands are full of blood, Wash you, make you clean, Put away from before my eyes the evil of your ways, Cease to do evil, Learn to do well.[7] With Isaiah these vehement apostrophes are but flashes of genius, but with Jesus the interior change becomes at once the principle and the end of the religious life. His promises were not for those who were right with the ceremonial law, or who offered the greatest number of sacrifices, but for the pure in heart, for men of good will. These considerations are not perhaps without their use in showing the spiritual ancestry of the Saint of Assisi. For him, as for St. Paul and St. Augustine, conversion was a radical and complete change, the act of will by which man wrests himself from the slavery of sin and places himself under the yoke of divine authority. Thenceforth prayer, become a necessary act of life, ceases to be a magic formula; it is an impulse of the heart, it is reflection and meditation rising above the commonplaces of this mortal life, to enter into the mystery of the divine will and conform itself to it; it is the act of the atom which understands its littleness, but which desires, though only by a single note, to be in harmony with the divine symphony. _Ecce adsum Domine, ut faciam voluntatem tuam._ When we reach these heights we belong not to a sect, but to humanity; we are like those wonders of nature which the accident of circumstances has placed upon the territory of this or that people, but which belong to all the world, because in fact they belong to no one, or rather they are the common and inalienable property of the entire human race. Homer, Shakespeare, Dante, Goethe, Michael Angelo, Rembrandt belong to us all as much as the ruins of Athens or Rome, or, rather, they belong to those who love them most and understand them best.
