“Then I fell at his feet and thought, Surely this is the hour of death, for the Lion (who is worthy of all honour) will know that I have served Tash all my days and not him. Nevertheless, it is better to see the Lion and die than . . . to live and not to have seen him. But the Glorious One bent down his golden head and touched my forehead with his tongue and said, ‘Son, thou art welcome.’ But I said, ‘Alas Lord I am no son of thine but the servant of Tash.’ He answered, ‘Child, all the service thou hast done to Tash, I account as service done to me.’ Then by reason of my great desire for wisdom and understanding, I overcame my fear and questioned the Glorious One and said, ‘Lord, is it then true . . . that thou and Tash are one?’ The Lion growled so that the earth shook (but his wrath was not against me) and said, ‘It is false. Not because he and I are one, but because we are opposites — I take to me the services which thou hast done for him. For I and he are of such different kinds that no service which is vile can be done to me, and none which is not vile can be done to him . . . ‘Dost thou understand, child?’ I said, ‘Lord, thou knowest how much I understand.’ But I also said (for the truth constrained me), ‘Yet I have been seeking Tash all my days.’ ‘Beloved,’ said the Glorious One, ‘unless thy desire had been for me thou wouldst not have sought so long and so truly. For all find what they truly seek.’
(C.S. Lewis, The Last Battle, 1956)
Those also can attain to salvation who through no fault of their own do not know the Gospel of Christ or His Church, yet sincerely seek God and moved by grace strive by their deeds to do His will as it is known to them through the dictates of conscience. Nor does Divine Providence deny the helps necessary for salvation to those who, without blame on their part, have not yet arrived at an explicit knowledge of God and with His grace strive to live a good life. Whatever good or truth is found amongst them is looked upon by the Church as a preparation for the Gospel. She knows that it is given by Him who enlightens all men so that they may finally have life.
