The “mighty wind” of Pentecost kindled that pure glow which was in the breast of Peter into a blazing fire and the fire seized upon all those who surrounded Peter. What they had believed only faint-heartedly before, became now an unshakable certainty, a certainty stronger than the certainty of Jewish persecution and Roman tyranny. They knew that “this Jesus hath God raised again … and He is exalted to the right hand of the Father” (Acts ii, 32, 33). That was the hour of the birth of the new faith and of the new Church. Why did the apostles believe? Because the Holy Spirit opened their eyes and they understood what had gone before: the manifestation of Jesus, His life, death and resurrection. The human form that veiled His Divinity became transparent to them, and now for the first time they all of them in a comprehensive and overwhelming intuition saw “the glory of God in the face of Christ Jesus.” All that they had guessed, and hoped, and believed of His mystery during His earthly career: all that was still overshadowed by doubt, uncertainty and worldly cares. Only at times, as at Caesarea Philippi (Mt. xvi, 16-17), had a deeper insight come to them. But it had not gripped the whole man, and under the influences of everyday circumstance, especially under the terrors of Good Friday, it soon fled into the remotest recesses of their consciousness. But now, in the fiery glow of their Pentecostal experience, their faith became a blazing flame. Then all those small and scattered rays combined to form one great radiance, a sure and certain realization of the Person of Jesus and all that that implied. So clear was this intuition and so strong this certainty, that those disciples were utterly changed men. Before, they had been men of little faith, with their continual questioning and their childish egotism; but now they went out into the civilized world full of the spirit of self- sacrifice and strong in soul. And they carried the new fire to the hovels of slaves and into the palaces of emperors. Twelve simple, uneducated fishermen revolutionized the world, and that with no other instrument than their new faith and their readiness to die for that faith.
