A weapon made of pure force springs into existence and attacks opponents at a distance, as you direct it, dealing 1d8 force damage per hit, +1 point per three caster levels (maximum +5 at 15th level). The weapon takes the shape of a weapon favored by your deity or a weapon with some spiritual significance or symbolism to you (see below) and has the same threat range and critical multipliers as a real weapon of its form. It strikes the opponent you designate, starting with one attack in the round the spell is cast and continuing each round thereafter on your turn. It uses your base attack bonus (possibly allowing it multiple attacks per round in subsequent rounds) plus your Wisdom modifier as its attack bonus. It strikes as a spell, not as a weapon, so, for example, it can damage creatures that have damage reduction. As a force effect, it can strike incorporeal creatures without the normal miss chance associated with incorporeality. The weapon always strikes from your direction. It does not get a flanking bonus or help a combatant get one. Your feats or combat actions do not affect the weapon. If the weapon goes beyond the spell range, if it goes out of your sight, or if you are not directing it, the weapon returns to you and hovers.
Each round after the first, you can use a move action to redirect the weapon to a new target. If you do not, the weapon continues to attack the previous round’s target. On any round that the weapon switches targets, it gets one attack. Subsequent rounds of attacking that target allow the weapon to make multiple attacks if your base attack bonus would allow it to. Even if the spiritual weapon is a ranged weapon, use the spell’s range, not the weapon’s normal range increment, and switching targets still is a move action.
A spiritual weapon cannot be attacked or harmed by physical attacks, but dispel magic, disintegrate, a sphere of annihilation, or a rod of cancellation affects it. A spiritual weapon’s AC against touch attacks is 12 (10 + size bonus for Tiny object).
If an attacked creature has spell resistance, you make a caster level check (1d20 + caster level) against that spell resistance the first time the spiritual weapon strikes it. If the weapon is successfully resisted, the spell is dispelled. If not, the weapon has its normal full effect on that creature for the duration of the spell.
Note that in all cases, the wording is such that "the weapon attacks", and never that the caster attacks.

Abjuration

Casting Time: 1 standard action
Range: Touch
Target: Creature touched
Duration: 1 round/level
Saving Throw: Will negates
Spell Resistance: No
Any opponent attempting to strike or otherwise directly attack the warded creature, even with a targeted spell, must attempt a Will save. If the save succeeds, the opponent can attack normally and is unaffected by that casting of the spell. If the save fails, the opponent can’t follow through with the attack, that part of its action is lost, and it can’t directly attack the warded creature for the duration of the spell. Those not attempting to attack the subject remain unaffected. This spell does not prevent the warded creature from being attacked or affected by area or effect spells. The subject cannot attack without breaking the spell but may use nonattack spells or otherwise act.
Note that the prohibition is only that "the subject cannot attack".
So am I correct in thinking that Spiritual Weapon is akin to Summon Monster in counting as a "nonattack spell" here?
