“For yourselves know perfectly that the day of the Lord so cometh as a thief in the night (1 Thess. 5:1-2). This is the truth to which the Christ’s Church has remained faithful. The true Church teaches, equally with the Apostle Paul, that the day of the Lord will come as a thief in the night and that no one knows the day nor the hour in which the Son of Man will come.”
(Elder St. Cleopha of Romania, ‘The Truths of Our Faith’)
