Every man receives generation, nourishment and teaching from his parents. Likewise the particular individuals who are parts of the domestic family help each other in the necessities of life. Communicant autem homines in uno ultimo fine beatitudinis, ad quam divinitus ordinantur. Oportet igitur quod uniantur homines ad invicem mutua dilectione. There should be a union of affection among those to whom belongs one common end.
Men share in the one common end of happiness, to which they are divinely ordained.
Therefore, men should be united to one another by mutual love. Homines autem dilecti sunt a Deo, quibus suiipsius fruitionem quasi ultimum finem praedisposuit. Oportet igitur ut, sicut aliquis fit dilector Dei, ita etiam fiat dilector proximini. Further, whoever loves someone, consequently loves as well those who are loved by that person and those associated with him. Humans are loved by God, and God praedisposed them so that their enjoyment of one another would be something like an ultimate end.
