Fr. Z expressed this sentiment back in the middle of the synodical proceedings in Rome on October 14th, but it's timely ever as it was then, as I'm increasingly convinced.
So we simply reiterate here what he said then: the weapons of our warfare are not carnal (physical). They include the following: Go to Confession. Pray the Rosary. Go to reverent celebrations of the Holy Mass (Father, as you know, stresses the Extraordinary Form). Fast. Offer up mortifications.
Now, more than ever, it is important not to let yourself stray into habitual sins, which emotionally cut you off from God and objectively cut you off from the graces of the Sacraments. Sin not only weakens you; it weakens the Church. Which is why the Sacrament of Reconciliation involves resolving your alienation from God but also reconciling yourself with the Church. Stay close to your Confessor(s).
