91 When churches are closed, when the Image of the Crucified is taken from the schools, the family remains the providential and, in a certain sense, impregnable refuge of Christian life. And We give thanks to God as We see that numberless families accomplish this, their mission, with a fidelity undismayed by combat or by sacrifice. A great host of young men and women, even in those regions where faith in Christ means suffering and persecution, remain firm around the Throne of the Redeemer with a quiet, steady determination that recalls the most glorious days of the Church's struggles.
