Comparative religion textbooks from a Catholic viewpoint Most Catholic text books about religion are about Catholicism, I asked my high-school aged daughter what she wants to study next year for religion class and she said she's like to know about other religions.  I'm having a hard time finding these kinds of books.
Most popular authors will write a book condemning this or that other religion, but I just want one that honestly compares them all without being wishywashy about which is better.  Otherwise, I think I'd have to piece together about a hundred books.
I would suggest a good apologetics book, because these are designed to refute the errors of false religions / belief systems and show how the Catholic religion is the only true one, e.g.:

Catholic Apologetics: God, Christianity, and the Church by Fr. John Laux
The Principles of Catholic Apologetics by Fr. T. J. Walshe

This more recent one compares Catholic theology and philosophy to that of other, non-Catholic belief systems (including even Eastern, Indian thought):

The Way toward Wisdom: An Interdisciplinary and Intercultural Introduction to Metaphysics by Benedict Ashley, O.P.Fr. Benny had a very interesting life, being an ex-Marxist before his conversion.

A classic comparing Catholic doctrine to Protestant/Lutheran doctrine is:

Symbolism, or, Exposition of the doctrinal differences between Catholics and Protestants as evidenced by their symbolical writings by Möhler, Johann Adam, 1796-1838&quot;Symbol&quot; in the sense of &quot;creed&quot; (σύμβολον, symballein, means a collection: &quot;It is from its being a collection of maxims of faith that the symbol [*The Greek {symballein}] takes its name.&quot;
