I have so many favorite saints it’s hard to list them all without forgetting some.
The Blessed Mother and St. Joseph are my top two.
The next bunch of go-tos would be St. Therese, St. Jude, St. Monica, St. Margaret Mary, St. Patrick, St. Anthony, and St. Padre Pio. Also my guardian angel and St. Michael.
I have a group that I pray to for cats and animal-related intentions: St. Francis of Assisi, St. Francis de Paola, St. Gertrude of Nivelles, St. Philip Neri, St. Martin de Porres
At the end of the Divine Mercy I usually pray to St. Faustina, St. Pope John Paul II, St. John XXIII, and St. Gertrude the Great.
Some others I pray to include St. Thomas More, Sts. Francesco and Jacinta Marto, St. Maximilian Kolbe, St. Elizabeth Seton, St. Katherine Drexel, St. John Neumann, St. John Henry Newman, St. Clement, St. Agnes, and various other Apostles (particularly St. Matthew who helps with financial matters).
People not yet canonized whom I pray to include Bl. Miguel Pro, Bl. Jerzy Popieluzko, Bl. Solanus Casey, Ven. Fulton Sheen, Ven. Patrick Peyton, Servant of God Emil Kapaun, Servant of God Lucia dos Santos, Servant of God Rhoda Wise, and Mother Angelica.
