As long as Archangel of Tithes is untapped, creatures can’t attack you or planeswalkers you control unless their controller pays for each of those creatures.
As long as Archangel of Tithes is attacking, creatures can’t block unless their controller pays for each of those creatures.
If you control an untapped Archangel of Tithes, your opponents can choose to not attack with a creature that must attack if able. The same is true with respect to an attacking Archangel of Tithes and a creature that must block if able.
