Unfortunately you are approaching this belief of the Church as a Protestant who insists that everything that a Christian must believe must be seen in black and white on the pages of a bible. Since you say you are a Catholic then you should know that the Sacred Tradition as well as Sacred Scripture form the basis of all Catholic belief, with the former never contradicting the latter.
Now you have been shown how the Church, as the official interpreter of Scripture, reads the passages indicating the existence of Purgatory, yet you insist that your subjective reading of Scripture necessarily indicates that the Church is wrong in its perennial belief in the purification of souls before they may enter into the fullness of the Beatific Vision.
A reading of this article would show you how the early Church Fathers regarded Purgatory:

And, as you say you are a Catholic, this from our present Holy Father should be of help to you unless you persist in your unbelief of the teaching of Christ through His Church:

Lastly, regarding the scriptural
bona fides of Purgatory, it is very clear from the Jewish record that “Gehenna” was not understood in the sense that we today understand “Hell.” For, in the ancient Jewish understanding, “Gehenna” could be either permanent and eternal (i.e., Hell) or it could be a temporary place of purgation and purification. This is seen quite clearly in Luke 16 itself. The element of this story which Protestants seem to consistently overlook is the fact that the Rich Man, who is being tormented in Gehenna, is (a) still in a Covenental relationship with Abraham (e.g. he still calls Abraham “father” and Abraham still calls him “my child”) and, even more notably, and (b) the Rich Man is deeply concerned for his brothers who are still alive! IOW, the Rich Man is still able to express selfless charity; for he asks Abraham to send Lazarus to warn his brothers when it becomes clear that there is nothing Abraham can do to cease his personal suffering. This alone shows us that the Rich Man is not in hell, for, in hell, it is impossible for a soul to be charitable - to express love for another. This is only possible in and through God and some kind of Covenantal relationship with God. Therefore, the Rich Man must be experiencing a period of purgation and purification, i.e., Purgatory.
