Man’s ultimate happiness does not consist in acts of moral virtue, because these are means

Context

“All things tend to be like God, who is the End of all things. Human happiness does not consist in carnal pleasures, honour, glory, wealth, worldly power, or goods of the body, and is not seated in the senses. Man’s ultimate happiness does not consist in acts of moral virtue, because these are means; it consists in the contemplation of God. But the knowledge of God possessed by the majority does not suffice; nor the knowledge of Him obtained by demonstration; nor even the knowledge obtained by faith.” source
