Please explain the bolded. This makes no sense to me.
I agree with Sean's friend.
If someone rejects the grace to labour in Our Lord's vineyard, He offers it to someone else.
Archbishop Vigano is a case in point. Surely he was raised up by God to do the job that Bishops Tissier, de Galarreta and Fellay no longer want to do, a la Bishop Fellay's "Rome has asked that we criticise less, and I agree".
As Bishop Williamson used to always say, the Good Lord cannot leave the Truth without a standard bearer in this world, and if the SSPX capitulates, He will simply raise up more Traditionalists to take its place.
