I promised to do whatever I can to assure that any children we may be blessed with will be raised in the Catholic faith.
This is correct, there is no longer an “obligation”, but a “promise” to do our best.
To the OP, I would gently make my aspirations known and perhaps remind her of the promise, with equal tact and diplomacy. But at the end of the day I would choose the path that would avoid unnecessary family conflict, while ensuring that it at least is a valid Trinitarian baptism and properly registered so a record exists of it somewhere. Then I would practice my own faith with vigour and devotion, to be an example to my children, so that they become
attracted to the Catholic faith, and make that choice later on.
In no way would I bully my wife into a situation she isn’t comfortable with.
As an aside to the OP, is your wife’s church one that allows/believes in infant baptism? Some only do adult, or “age of reason” baptism. If it’s the latter, perhaps you can suggest a Catholic baptism while leaving the door open to the child changing his/her mind at the age of reason.
Regardless of how things go with the baptism, as a parent in an ecumenical marriage one has to be prepared for the child to eventually reach the age of reason and make a choice that is a disappointment to us. In this case, the child may decide to grow in the Catholic faith, the Evangelical faith, some other faith, or no faith at all. It is the “beau risque” of free will, without which faith itself would be meaningless. Even in a purely Catholic-to-Catholic marriage, there is a great chance that the child may at some point reject the faith. Again, that’s a risk of free will.
As a Catholic you have the obligation to raise your children catholic.
No, this is no longer true. UpUp’s answer was the correct one, a promise to do one’s best. Not an obligation.
Faith should never be a straight jacket, nor an opportunity for bullying.
