"The praying attitude of the Church in the first days after the Ascension, when the disciples waited for the Spirit, should be the Church’s attitude still. . . . [P]rayer is the main work of a ministry. And no more mischievous and misleading theory could be propounded, nor any one more dishonoring to the Holy Spirit, than the principle . . . that because the Spirit was poured out at Pentecost, the Church has no need and no warrant to pray any more for the effusion [outpouring] of the Spirit of God. On the contrary, the more the Church asks for the Spirit and waits for His communication, the more she receives."
