St. Ambrose
Eph 3, 8-12
I, who am less than the least of all God’s holy people, have been entrusted with this special grace, of proclaiming to the gentiles the unfathomable treasure of Christ and of throwing light on the inner workings of the mystery kept hidden through all the ages in God, the Creator of everything. The purpose of this was, that now, through the Church, the principalities and ruling forces should learn how many-sided God’s wisdom is, according to the plan which he had formed from all eternity in Christ Jesus our Lord.
