Can catholics go to Lutheran services?

[Contarini]

As long as you fulfill your Sunday obligation, you could go, but Lutherans lack orders & cannot confect the Eucharist (or believe it’s symbolic)

Lutherans do not believe this. In fact, LCMS Lutherans do a much better job of catechizing their people, so probably more of them (proportionately) believe in the Real Presence than of Catholics.

so what is the point?

To worship God with one’s brothers and sisters in Christ.
