In 1939 four young couples approached their parish priest, Father Henri Caffarel, and asked his help in exploring the richness and joy of their Sacrament of Matrimony. From these simple beginnings T.O.O.L. has grown to a worldwide movement, present on all continents of the world and involving about 4,000 couples in the United States. The formal charter for the Movement was adopted on December 8, 1947. It is recognized by the Holy See as an Association of Faithful of Private Right under the Pontifical Council for the Laity. The Movement is guided by an International Responsible Team in concert with a College of Super-Regional Couples who serve their various countries.

In January 2009 Pope Benedict XVI held a private audience with the International Leadership Couples of Teams gathered in Rome, urging their continued work with married spirituality.

It encourages its members to pray and share together, help one another grow in knowledge and love of the Lord; and to bear witness to that love. T.O.O.L. does not impose a particular type of spirituality on its members. The Movement simply seeks to help its members advance, as a couple, along the path shown by Christ.
A key feature of the T.O.O.L. method is the monthly meeting that consists of:
To promote personal and couple spiritual growth, T.O.O.L. proposes that its members undertake a number of specific practices called "endeavors". These endeavors aim to keep couples focused on growth in mutual love and love of God. The Team provides the support and encouragement needed to persevere. The six Endeavors are:
