A Handbook of Spiritual Ecumenism (Hyde Park: NY, New City Press, 2007), published by the Pontifical Council for Christian Unity, provides numerous suggestions for Catholics engaging in private prayer for Christian unity:
-Insert, where possible, particular intercessions for Christian unity in the liturgical prayer of the Church, including the Liturgy of the Hours and Office of Readings;
-Offer daily prayer or devotions for the intention of Christian unity. Examples can include the Morning Offering, praying the Rosary or Eucharistic adoration;
-Seek Christian unity through fasting, penance and personal conversion;
-Unite hardships and sufferings with Christ for the intention of Christian unity.
