"Rise and walk"

From F. F. Bruce's commentary on today's reading from Acts:

According to Cornelius a Lapide, Thomas Aquinas once called on Pope Innocent II when the latter was counting out a large sum of money. "You see, Thomas," said the Pope, "the church can no longer say, 'Silver and gold have I none.'" "True, holy father," was the reply; "Neither can she now say, 'Rise and walk.'" The moral of this tale may be pondered by any Christian body that enjoys a fair degree of temporal prosperity.
