Because our Lord came for the sinners. What good is accomplished by tossing them out of the Church. The proper and most Christ like approach is to correct them - first in private then, if necessary, publicly. The bishop is following in the footsteps of Christ, the Shepherd.
Agreed, Jesus did come to save us sinners. However, our Lord clearly indicated that eventually...if someone who claims to be a brother (or sister) is intransigent, and won't be corrected privately or publicly, than they must be thrown out of the Church...and this must be public.
Pelosi and other politicians like her--who base their careers on being pro-abortion AND Roman Catholic fit this description perfectly.
"If your brother sins against you, go and show him his fault, just between the two of you. If he listens to you, you have won your brother over. But if he will not listen, take one or two others along, so that 'every matter may be established by the testimony of two or three witnesses.'If he refuses to listen to them, tell it to the church; and if he refuses to listen even to the church, treat him as you would a pagan or a tax collector." (Matt. 18:15-17)
Oddly enough this passage is immediately followed by one commonly attributed to establish Roman Catholic authority: "I tell you the truth, whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven."
What good is a Church's authority if never exercised?
Jesus had no trouble clearing the temple of the money changers. Pelosi, Biden, Kennedy, Kerry, etc.... are no better.
The Catholic Church does not need members that will lead others into sin. Much better to kick these few out to send a clear message to the rest of the flock. They can always publicly recant their errors, go to confession and come back into communion.
Jesus welcomed the woman caught in adultery when she mended her ways.
By their own actions and beliefs, they have already tossed themselves out of the Church. If they refuse to repent, they have denied the faith and are worse than an unbeliever.
All they need to do is go to Confession, stop supporting abortion and refuse to allocate taxpayer money to fund it.
