29. The more boldly haters of God and enemies of Christian teaching attack Jesus Christ and the Church He founded, the more readily must priests and all Catholics, by spoken word, popular writings, and good example, resist them, respectful ever of individuals, but defending the truth. And if to do this they must overcome many obstacles, and even sacrifice time and money, they must never refuse, mindful of the maxim that Christian virtue must do and suffer much, but God Himself will reward it most generously with everlasting happiness. 30. There is always a bit of martyrdom in such virtue if we really want to strive day by day for a greater perfection of Christian life. For not only by shedding of blood is the witness of our faith given to God, but also by courageous and constant resistance to the lure of evil, and by the complete and generous dedication of all that we are and have to Him Who is our Creator and Redeemer, and will one day be our never ending joy in heaven. Pope Pius XII, INVICTI ATHLETAE, MAY 16, 1957
