28 Let Our commands and Our wishes be confirmed by the words so full of apostolic charity which the blessed Paul addressed to the Romans: "I beseech you therefore brethren, be reformed in the newness of your mind; he that giveth, with simplicity; he that ruleth, with carefulness; he that showeth mercy, with cheerfulness. Let love be without dissimulation. Hating that which is evil; cleaving to that which is good; loving one another with the charity of brotherhood; with honor preventing one another; in carefulness, not slothful; rejoicing in hope; patient in tribulation; instant in prayer. Communicating to the necessities of the saints. Pursuing hospitality. Rejoice with them that rejoice; weep with them that weep; being of one mind to one another; to no man rendering evil for evil; providing good things not only in the sight of God but also in the sight ,(16) of men.
