14 All ought to note - what to you, Venerable brothers and beloved sons, is evident - that We intensely desire that the time will soon come when the financial means furnished by the Chinese people will suffice for the needs of the Church in China. However, as you well know, the offerings received for this from the other nations have their origin in that Christian charity through which all those who have been redeemed by the sacred blood of Jesus Christ are necessarily united to one another in fraternal alliance and are spurred by Divine Love to spread everywhere, according to their strength, the kingdom of our Redeemer. And this not for political or any profane ends, but only to put into useful practice the precept of charity that Jesus Christ gave to us all, and through which we are recognized as His true disciples (Cf. John 13. 35). Thus have the Christians of all ages voluntarily done, as the Apostle of the Gentiles related of the faithful of Macedonia and Achaia, who willingly sent their offerings "for the poor among the saints at Jerusalem" ( Rom . 15. 26), and as the Apostle exhorted his children in Christ who lived in Corinth and Galatia to do the same thing (Cf. I Cor . 16. 1-2).
