Thus says the LORD:

If you remove from your midst oppression, false accusation and malicious speech; If you bestow your bread on the hungry     and satisfy the afflicted;

Then light shall rise for you in the darkness, and the gloom shall become for you like midday; Then the LORD will guide you always and give you plenty even on the parched land. (Isaiah)

“Remember, white supremacy is not just about individual acts of racism, but rather it is a system of oppression that seeps into and often forms the foundation of many of the regular spaces where you spend your time—school, work, spiritual spaces, health and wellness spaces, and so on. All these spaces are often protected from overt and individual acts of racism while allowing covert and systemic racism to be a part of the accepted culture through white silence.”

The operative word in each citation is “oppression.” Racism is a sin, a sin because we oppress people and treat people as less than they are. Silence in the face of oppression makes us complicit in white supremacy. Further in the chapter Isaiah speaks about becoming “repairers of the breach.” When we speak out about race and racism, we repair the breach which separates whites and BIPOC.
