12 How, then, can We desist, Venerable Brethren, when We love those children of Ours so intensely in the heart of Jesus Christ ( Philip 1, 8); how can We desist from appealing again and again to you all individually and collectively and to all throughout the world who, like you, are inspired with a sense of mercy and piety, so that the full force of Christian charity - and it is a mighty force - may be pooled by willing and generous souls in order to mitigate and relieve their piteous condition.
