Positive reasons give someone something to build on rather than to be filled with spite and hate. Must agree with the bishop.
Salvation, I agree with you about the importance of being positive, but I don't think we can assume that the Anglicans are full of spite and hate. I think the separation from Rome has always been an artificial one, and I think that many Anglicans have been put into a very bewildering position with the changes taking place in the Anglican Communion. I think they have the same right to be in the Catholic Church as I do, and I would rather see a bishop welcoming people.
As I understand it, Anglicans would likely go through a year long RCIA class, and it will take positive reasons for people to maintain the commitment to doing that.
It seems to me that a lot of Anglicans have done a much better job of being Christian and working to maintain principles in the face of adversity than I have.
