"Two wills", Dumbledore and Harry: "Let this cup pass..."

Someone pointed out that Dumbledore's drinking of the potion before his death in Half-Blood Prince parallels Christ's plea in the garden to let the cup of suffering pass from him "but not my will, but Thy will be done." The Fathers of the Church always saw the two wills of Christ, human will and divine will, struggling in the gospel scene. In HBP, the two wills are symbolized by Harry and Dumbledore. Dumbledore, serving the more noble purpose and in his "right mind" before beginning to drink, entrusts Harry with the task of forcing him to drink against any protest which he might make later when his human weakness is under duress. Only Harry's trust and obedience of Dumbledore, Harry's service of the "noble purpose", allows the cup to be fully drunk, thus bringing the two wills back into union.
