O God, with Whom is the well of life, and in Whose light we see light; increase in us, we beseech Thee, the brightness of Divine knowledge, whereby we may be able to reach Thy plenteous fountain; impart to our thirsting souls the draught of life, and restore to our darkened minds the light from heaven—Amen.

Mozarabic, before A.D. 700

Almighty God our heavenly Father, without Whose help labor is useless, without Whose light search is vain, invigorate my studies, and direct my inquiries, that I may, by due diligence and right discernment, establish myself and others in Thy holy fiiilh. Take not. O Lord. Thy Holy Spirit from nie; let not evil thoughts have dominion in my mind. Let me not linger in ignorance, but enlighten and support me. for the sake of Jesus Christ our Lord—Amen.

Samuel Johnson (1709-1784)
