Congress of the Philippines

Symbols of Authority
A seal is defined as an impressed device attached to a paper for purposes of authentication, and the instrument, by which it is made is a seal press or a stamp. The seals of the Republic are the seals of office — not the man occupying the position — hence the text "Official Seal" on the circular border of the seal. Most seals of various government agencies feature symbols pertinent to and symbolic to the functions of the agency.
On September 23, 2015, the House of Representatives adopted a new seal through House Resolution No. 233 which is reflective of the character and tradition of the institution.

The Seal is in circular form with the National Coat-of-Arms of the Republic of the Philippines but without the scroll and the inscription in the center.
The mace is the symbol of authority of the Senate. Its symbolism strongly holds for the authority of the President of the Senate. It is also the authority of the Sergeant-at-Arms when enforcing order in the Senate. The mace is an essential part of the regalia of the Senate. Without it, the Senate is not considered to be properly constituted. When the Senate is in session, the mace is displayed at the Senate President’s rostrum. Otherwise, it is kept under the custody of the Sergeant-at-Arms. The Sergeant-at-Arms, custodian of the mace, is charged with its use when necessary to preserve order. When the occasion calls for it, or when there is disorder in the session hall, he shall lift the mace from its pedestal and present it before an unruly member in order to restore order or quell boisterous behavior in the Chamber.
The Mace of the House is a symbol of authority, which is displayed at the foot of the Speaker's Rostrum whenever the House is in session. It serves as the warrant for the Sergeant-at-Arms in enforcing order in the House upon instruction of the Speaker.

The Gavel is used by the President of the Senate for commanding attention whenever the Senate is in session.
The Gavel is the symbol of authority of the Speaker during sessions; and, in his absence, by the Speaker Pro Tempore or any member designated to perform the duties of the Presiding Officer.
