Va. Const. art. IV, § 16

The General Assembly shall not make any appropriation of public funds, personal property, or real estate to any church or sectarian society, or any association or institution of any kind whatever which is entirely or partly, directly or indirectly, controlled by any church or sectarian society. Nor shall the General Assembly make any like appropriation to any charitable institution which is not owned or controlled by the Commonwealth; the General Assembly may, however, make appropriations to nonsectarian institutions for the reform of youthful criminals and may also authorize counties, cities, or towns to make such appropriations to any charitable institution or association.
