Irenaeus

Inasmuch, then, as the Church offers with single-mindedness, her gift is justly reckoned a pure sacrifice with God. As Paul also says to the Philippians, "I am full, having received from Epaphroditus the things that were sent from you, the odour of a sweet smell, a sacrifice acceptable, pleasing to God." For it behoves us to make an oblation to God, and in all things to be found grateful to God our Maker, in a pure mind, and in faith without hypocrisy, in well-grounded hope, in fervent love, offering the first-fruits of His own created things. And the Church alone offers this pure oblation to the Creator, offering to Him, with giving of thanks, [the things taken] from His creation.
