it is the only place where you can be sure that you can get forgiveness of your sins.

The only place from which one can get forgiveness of sins is from God. The Catholic Church cannot forgive your sins - Neither can any other.. only God can do that.

Only God can forgive sins? Eh? You might want to check again: (Jesus) said to them again, "Peace be with you. As the Father has sent me, so I send you." 22 And when he had said this, he breathed on them and said to them, "Receive the holy Spirit. 23 Whose sins you forgive are forgiven them, and whose sins you retain are retained."
