But the Apostles are compared to old skins, who are more easily burst with new wine, i. e. with spiritual precepts, than contain them. Hence it follows, Else the new wine will burst the skins, and the wine will be spilled. But they were new skins at that time, when after the ascension of the Lord they received the Holy Spirit, when from desire of His consolation they were renewed by prayer and hope. Hence it follows, But the new wine must be put into new bottles, and both are preserved.
