On Prayer
Tertullian · early-church-fathers
We Must Be Free Likewise from All Mental Perturbation.
Nor merely from anger, but altogether from all perturbation of mind, ought the exercise of prayer to be free, uttered from a spirit such as the Spirit unto whom it is sent. For a defiled spirit cannot be acknowledged by a holy Spirit, nor a sad by a joyful, nor a fettered by a free. No one grants reception to his adversary: no one grants admittance except to his compeer.
