10. My children, within the sentence: Without charity there is no salvation, is enclosed the destiny of mankind, both on Earth and in Heaven. On Earth, because beneath the shadow of this banner all may live in peace, and in Heaven, because those who have practised it will find grace in God's eyes. This phrase is the celestial beacon, the luminous column, which will guide mankind in life's desert, putting all on the right path to the Promised Land. It shines in Heaven as a saintly halo on the brows of the chosen ones, and on Earth it is engraved on the hearts of those to whom Jesus has said: "Go to the right and receive the blessing of My Father". You will recognise them when they come by the aroma of charity that spreads around them. Nothing can indicate with more exactitude nor summarize so well mankind's obligations, as this divine maxim. Spiritism could not better prove its origin than present it as its rule, because it is a reflection of the most pure Christianity. Humanity will never go astray if it takes this as its guide. So then, my dear friends, dedicate yourselves to the understanding of the deep meaning behind these words and the consequences of their application and then discover for yourselves all the many ways in which they may be applied. Submit all your activities to be administered by charity and your conscience will respond. Not only will it cause you to avoid practising evil, but it will also make you practise goodness, in as much as a negative virtue is not enough; it is necessary to possess an active virtue. Therefore in order to do good there is always the need for the action of willpower, whereas in order to not practise evil it is sufficient to be inert o? unconcerned.
My friends, give thanks to God for having permitted you to enjoy the enlightenment of Spiritism. Not that those who possess this enlightenment are the only ones who will be saved, but because it helps you to understand the teachings of Christ, so making you into better Christians. Therefore make every effort so that your fellow beings, on observing you, are induced to recognise that the true Spiritist and the true Christian are one and the same, given that all those who practise charity are the disciples of Jesus, without putting any embargo on whatever sect they may belong to. - PAUL, the Apostle (Paris, 1860).
