No, but, she can act as stand in for the chosen sponsor, should the sponsor not be able to be physically present at the Confirmation Mass.
No, you would need to be confirmed to be a sponsor.
Yes, a priest can be a confirmation sponsor in the Catholic Church. Canon law states that a baptized Catholic who is confirmed, has received the Eucharist, is in good standing with the Church, and is not the parent of the one being confirmed can serve as a sponsor. Since priests meet these criteria, they are eligible to be confirmation sponsors.
No. Only the Confirmation candidate him/herself speaks.
Yes they can.
A sponsor can be male or female, and must be at least age 16, a Catholic in good standing, and confirmed.
A sponsor is not required at Confirmation, although many bishops allow them, or even require them. Only one sponsor is customary where it is required, if you would like more than one, you would have to have your pastor check with the Bishop.
Only if it's a present for the Confirmation candidate.
Yes, no problem. If the deacon is assisting the bishop at the Confirmation, he can step down to sponsor at Confirmation then return. If he is not assisting the bishop, he simply sits in the congregation with the other sponsors, without vesting.
A Confirmation sponsor is a confirmed Catholic in good standing who mentors the Confiramation candidate before he or she is confirmed. Traditionally the Confirmation sponsor is a Godparent (connecting Baptism to Confirmation), but does not have to be.
Usually the young person's godparents.
Someone who stands in for the sponsor if the sponsor cannot make the ceremony. The proxy should also be Catholic and Confirmed.
