How can “gay” people practice chastity since the thing that makes them “gay” is their sexual proclivities?
Chastity for “gay” people is exactly the same as chastity for “straight” people. It calls for sexual continence except for acts in the procreative form in the context of the sacrament of matrimony. It requires striving for purity of heart and mind and intention toward all people as a reflection of divine love.
