Oh, like the Church.

The Power of the Keys (Matthew 16:19) finds its explanation in Isaiah 22, where "the key of the house of David" is conferred upon Eliacim, the son of Helcias, as the symbol of plenary authority in the Kingdom of Juda.

It is a grant of ecclesiastical authority in a sense peculiar to St. Peter and his successors in its fullness, but to the bishops according to their role in the Church. The potestas clavium includes:

- the power of order, namely power exercised in regard to sacrifice and sacrament,

- the power of jurisdiction, and

- the power to define in questions of faith and morals. 

Only God is sovereign, Maker and Sustainer of all that is, and Supreme Author of Laws.

In fact, if the Church tried to override God's commands on things such as orders or marriage or abortion it would be trying to infringe on God's sovereignty.
