At present friendship is juxtaposed to love. This is contrary to the meaning of friendship that has been worked out by the classical (Latin) tradition, which has always pointed to friendship as the highest level of love. The essence of friendship between the fiancé and fiancée is cooperation in morally perfecting each other, and of friendship between the spouses also in perfecting their children in the process of raising them. Basing the two kinds of friendship on utility goods or on pleasure only is a threat to them. Only spiritual friendship perfects people in their attitude of service, which is a condition for building up sanctity in each other.
