St. Gregory the Great

The proof of love is in the works. Where love exists, it works great things. But when it ceases to act, it ceases to exist.

St. Thomas Aquinas

Just as in one man there is one soul and one body, yet many members; even so the Catholic Church is one body, having many members. The soul that quickens this body is the Holy Spirit; and therefore in the Creed after confessing our belief in the Holy Spirit, we are bid to believe in the Holy Catholic Church.

St. Therese of Lisieux

Leave consolations to God, to do with them as best pleaseth Him. But prepare thou thyself to bear tribulations, and account them the greatest consolations.

Vatican II's Apostolicam Actuositatem #33

The most holy council, then, earnestly entreats all the laity in the Lord to answer gladly, nobly, and promptly the more urgent invitation of Christ in this hour and the impulse of the Holy Spirit. Younger persons should feel that this call has been directed to them especially and they should respond to it eagerly and generously. Through this holy synod, the Lord renews His invitation to all the laity to come closer to Him every day, recognizing that what is His is also their own (Phil. 2:5), to associate themselves with Him in His saving mission. Once again He sends them into every town and place where He will come (cf. Luke 10:1) so that they may show that they are co-workers in the various forms and modes of the one apostolate of the Church, which must be constantly adapted to the new needs of our times. Ever productive as they should be in the work of the Lord, they know that their labor in Him is not in vain (cf. 1 Cor. 15:58).

Padre Pio

Serve God with a joyful spirit because God is the God of joy.

Apostolicam Actuositatem #4

The perfect example of this type of spiritual and apostolic life is the most Blessed Virgin Mary, Queen of Apostles, who while leading the life common to all here on earth, one filled with family concerns and labors, was always intimately united with her Son and in an entirely unique way cooperated in the work of the Savior. Having now been assumed into heaven, with her maternal charity she cares for these brothers of her Son who are still on their earthly pilgrimage and remain involved in dangers and difficulties until they are led into the happy fatherland. All should devoutly venerate her and commend their life and apostolate to her maternal care.

It is our choices...that show what we truly are, far more than our abilities.
