"Let's Get Started" Lenten Parish Mission in Tubac, AZ.
2026-02-24 18:00 - 2026-02-26 19:30
Meet me in Tubac, Arizona, at St. Ann’s Catholic Church for a Lenten Parish Mission “Let’s Get Started” February 24-26.
Retreat sessions will be offered each evening at the hall behind the parish office from 6:00 pm to 7:30 pm. 18 Calle Baca, Tubac, AZ, Tubac, Az 85646.
Mass will be offered each day at 9:00 am at St. Ann’s Catholic Church: 11 Calle, Iglesia, Tubac, AZ 85645.
There will be opportunities for individual appointments of 30 minutes each with Father Nathan each day from 10:00 am to 12:00 pm. Please call the office to schedule (520) 398-2646
Session One: Tuesday, February 24th: Where Do I Start?
“It’s always best to start at the beginning,” said Glinda to Dorothy. We will prayerfully examine how we got our start on this earth, who and what we are, and where we’ve been so far. Once we have a sense of our current starting point, we’ll be better prepared to start something new.
Session Two: Wednesday, February 25th: Being in Re-Mission.
“Good news! You’re in remission!” This might be good medical news about one’s health and vigor after a period of trial. You might have a sense of having been given more time and new possibilities. Together, we’ll look at how we might make ourselves available to the Spirit’s next dream for us.
Session Three: Thursday, February 26th: Dying, Rising, and New Beginnings.
Lent and Easter remind us that we don’t wither away. We die and are reborn according to the pattern made plain to us by Jesus and his beloved followers. What new adventures might await us as we grow into our undying, eternal selves?

The Gospel of John is a testament to love overflowing, serving as the central theme that connects the Last Supper to the Easter events. It transcends human emotion, embodying a “super-abounding” divine power that emanates from God to Jesus, and then spreads through believers to the world.
