Actually, that passage has lots of great Catholic Theology in it. The Apostles received a ministry of reconciliation [us] and of course Paul got this how, by being linked to the Peter, James, John and other Apostles and what exactly is the ministry of reconciliation, that it the Apostles are ambassadors for Christ [ambassador meaning like his representative or agents acting on his behalf, etc] and God is making an appeal through us [Apostles] we implore you on Christ behalf, etc.
Ties well to the ordained clergy and having the authority by Christ to forgive sins and reconcile in his name and because of him, that is God acts and works to make himself known through the Church. Lots of Catholic Ecclesiology and sacramental theology present in that passage you cited.
ALL believers have the ministry of reconciliation.
We are ALL to go out preaching the gospel and doing our best to lead people to Christ that they might be saved.
It’s not a job to be foisted off onto paid clergy.
