It seems to be true for the Institute for Creation Research:
As a missionary organization, ICR is funded by God's people. The great majority of its income is provided by individual donors who desire to proclaim God's truth about origins. We invite you to join this key group of supporters.Gifts can be designated for research, the graduate school, seminars, or any specific part of the ICR ministry. All others will be used where most needed. We pledge to use them wisely and with integrity. As a 501(c)(3) non-profit organization, your donations are tax exempt.
