The Torah tells us that one of the reasons cohanim, priests, are to be sanctified is specifically because the priest offers the bread of your G-d (L. 21:8).
Separately, the Torah tells us about offering bread to G-d:
When you enter the land to which I am taking you, and you eat of the bread of the land, you shall set some aside as a gift to G-D: as the first yield of your baking, you shall set aside a loaf as a gift; you shall set it aside as a gift like the gift from the threshing floor. You shall make a gift to GOD from the first yield of your baking, throughout the ages. (N. 15:17)
Offering some of our bread is thus a specific commandment. Bread, of course, involves a great many steps and very hard work: we can see it as the product of a partnership both between man and G-d, as well as within a society (from planting to weeding to harvesting to drying, milling, kneading, rising and baking – the enterprise requires, at the very least, a village!). Despite all our hard work, we give G-d the credit.
We sanctify the priests who offer bread to G-d. But we do more than that: we also sanctify even the non-priests who bake bread and offer it to G-d!
The mere act of baking bread and setting it aside for G-d is a holy act. It connects our labor with G-d’s deliverance, it connects earth with heaven (our energies projecting back up to heaven, as part of the Reiac Cycle). And, the Torah is telling us, it elevates those of us who engage in that act.
Throughout most of human history (and especially in the ancient world), women have been largely responsible for the final stages of bread making: grinding, kneading, and baking.
Which means that the Torah is suggesting that women who offer challah/bread to G-d are to be honored and sanctified, for the same reasons we honor the priests: they offer the bread of your G-d.
