"Truth calls His disciples back from a private to a common joy when He admonishes them as they return from preaching, delighting in the subjection of demons, saying: 'In this rejoice not...but rather rejoice because your names are written in Heaven (Luke 10:20).' For not all the elect cast out demons but the names of all the elect are nevertheless preserved, written in Heaven. Therefore the disciples are enjoined to lay aside their private joy and rejoice in common, eternal felicity."
Gregory the Great
There's our Anglican problem: we can't glimpse the bright spiritual joy big enough to eclipse the dim little satisfactions of our interest groups.
