Song of Songs 7:13

The mandrakes give a fragrance, and at our gates are all manner of pleasant fruits, new and old, which I have laid up for you, O my beloved.

Ambrose of Milan

AD 397
The old things according to the flesh have passed away; all have become new. If the scribe instructed in the kingdom of heaven knows not these things, he is like the householder who brings from his treasure new things and old, not old without new, or new without old. So the church says, “The new and the old I have kept for you.” The old have passed away, that is, the hidden mysteries of the law have all been made new in Christ. - "Letter 73, To Laymen"

Ambrose of Milan

AD 397

The church is a field of this sort, fecund in diversity. - "On Virginity 6.34"
