It depends what is meant by paths. For example, the contemplative religious life and the married life are both different paths in which one can attain to salvation.
However, as there is only one way to salvation in the sense that Christ is the only way (the way, the truth, and life). There is the narrow path and there is the broad path that leads to destruction. The only way is Christ’s way, as His Mystical Body has traveled it, marked it, and taught it, since the Apostles.
The fact that someone who in “good faith” is mistaken or ignorant about Christ and His Church is not necessarily excluded from salvation does not mean their mistaken way is another valid way–rather, if they have faith (that is, they desire to abandon their own will to divine wisdom–which Christ is) they are on the one path interiorly, if not exteriorly.
