“And how does the Catholic Encyclopedia deny that this was the teaching of the Church? “
The Catholic Encyclopedia’s full entry is clear that these were abuses, not Catholic doctrine. Those who want to see the Truth will see that.

WRONG! The Catholic Encyclopedias full entry is indeed clear that there were abuses , but NOT that granting a plenary indulgence for voluntarily contributing to the building of the church, as described, was an abuse, which is the issue.
Instead, rather than the Bull Sacrosanctis salvatoris et redemptoris by Leo X being an abuse, http://www.newadvent.org/cathen/07783a.htm affirms "alms deeds" "being prescribed in the granting of an indulgence," and that "among the good works which might be encouraged by being made the condition of an indulgence, alms giving would naturally hold a conspicuous place." Which did lead to abuses, as were other things, but not that alms giving for an indulgence was itself an abuse.
As for "those who want to see the Truth will see that," yes indeed, those who want to see the Truth can see that a way to get an indulgence was to give the Church money, via an indulgence being granted by the papal Bull Sacrosanctis salvatoris et redemptoris for those who would contribute to the building of St. Peter's, under the condition of confession, and that this was not an abuse. Moreover, as stated, the Catholic Encyclopedia (in its entry on Leo X) affirms that "Rome permitted him [Albert of Brandenburg] to have preached in his territory the plenary indulgence promised all those who contributed to the new St. Peter's."
That the forgiveness of sins was sold for money regardless of contrition would be an error, and I stated this condition, and further confirming what I said, the Catholic Encyclopedia absolves Tetzel of this charge in its entry on him, while affirming that his error was preaching "plenary indulgence for the dead on the mere gift of money, without contrition on the part of the giver."
Those who want to see the Truth can see that.
