Thomas Aquinas,
Summa Theologiae — Question 86 - OF OBLATIONS AND FIRST-FRUITS…
“ Whatever is given to the poor is not a sacrifice properly speaking; yet it is called a sacrifice in so far as it is given to them for God's sake. In like manner, and for the same reason, it can be called an oblation, though not properly speaking, since it is not given immediately to God. Oblations properly so called fall to the use of the poor, not by the dispensation of the offerers, but by the dispensation of the priests. ”
