Can I use Strike from Spiritual Weapon in Tandem Strike?

[Garrise]

As subject, if not, is there any divine spells that allow me to make melee Strike if I don't have any type of melee attack?
Thank you very much

No, you do not Strike with Spiritual Weapon, you use the Sustain a Spell action.

That means you can't use it with the feat Tandem Strike, because it specifically calls out the Strike action, but you can Sustain a Spell while using Act Together.
