Portate Cross
The Portate Cross relates to an event over 2,000 years ago.
But first, let's dismiss the double-barred slanting line show on the right. That's a mathematical symbol for "not equal", and not a Christian cross at all. It's also a symbol sometimes used by White supremacists who want to distinguish other races as not equal to themselves.
And we couldn't agree more. The vast majority of "other races", and the vast majority of those in the same race, are not equal and passionately would hate to have any connection at all to White supremacists; most of whom are ignorant of basic biology. For them, malevolence is much easier.
'Portate' is from the Latin portare 'to carry'. From this word we get words like 'portable' and 'porter'. In heraldry, this cross may be referred to as Angled (Fr: Anglée) but this term is not as descriptive as 'portate'.

There are many other diagonal crosses; for example in the logo of the Christian Methodist Episcopal Church (CME) and the more generic St. Andrew's Cross, as seen in the logo of the Christian Church (Disciples of Christ) (CCDC).
A cross is usually shown erect, as it would be when used for crucifixion. The Portate Cross differs in that it is borne diagonally, as it would be when the victim bears the cross-bar over his shoulder as he drags it along the ground to the crucifixion site.
The Portate Cross reminds us of the cross carried by Jesus prior to his Crucifixion and that any cross we bear in his name will be nothing compared to his suffering. (See also Agnus Dei).
