Something regularly used in quotations is called the "ellipsis" (from the Greek: ἔλλειψις -- "omission"). It is indicated with three dots in a row, and signifies that one is omitting part of the quotation. If one is making a change to a quotation to make it more grammatical, one puts the change in square brackets "[" and "]". Perhaps the Collegium Diploma Molendini left this out of your training.

You wrote "Christianity isn't about vague 'values'", it's about an intimate relationship which Jesus Christ". Using ellipses and square brackets, I rendered this as "'Christianity ... [is] about an intimate relationship which Jesus Christ". This is a quite acceptable usage by those for whom English is a native language.

No, I quoted you accurately, and you would rather whinge, pretending I didn't, than admit that YOU had misstated what Pope Francis had said. Once again, you are shown to be in the wrong, and you blame someone else rather admit to a mistake. Your arrogance shines forth.
