If you sin, confess it…

First of all, do everything you can to avoid offending God, but if unfortunately you should commit sin, do not let the devil prevail upon you to not confess it. Remember that the confessor is a father who is eager to do all he can for you and [to] protect you from all possible harm.
–Saint John Bosco (1815-1888)

Believe only those…

Cease troubling about these fears, then, sisters; and never pay heed to such matters of popular opinion. This is no time for believing everyone; believe only those whom you see modeling their lives on the life of Christ. Endeavor always to have a good conscience; practice humility; despise all worldly things; and believe firmly in the teaching of our Holy Mother Church.
–Saint Teresa of Avila (1515-1582)
